I can't reproduce this with kernel.org 2.6.15 on an HP rx2600.

I'm running Debian "testing" on this box.

I tried both commands and both seem to work fine.
At least they didn't hang.
I suggest looking at firmware interaction problems.

I'm upgrading system firmware so I can upgrade to 2.6.16.
(SAL needs to be updated)
If the problem is reproducable on 2.6.16, I'll post again.

My HP rx2620, HP zx2000 and Intel Tiger are all running 2.6.16-gitlatest and
none of them hang on hwclock or ntpdate either.

The config file listed in the bugzilla has a zillion differences from
arch/ia64/defconfig ... and chance of trying with a kernel based on
this config?

We've put 3 2.6.16 builds in Debian/sid so far (2.6.16-[234]).
This user didn't specify which one, but I was unable to reproduce on
my HP rx2600 with either -3 or -4, and I see nothing in the -3
changelog that looks like it could've caused this behavior:

Comment 5 Sergey 2006-04-02 23:40:13 UTC
I'm compile kernel 2.6.15 and install unstable debian kernel 2.6.16-3,4, but 
thet not to help.

Comment 8 john stultz 2006-07-10 11:35:53 UTC
This bug is a little stale.

Sergey: Any update? Does this issue still exist w/ 2.6.17 or 2.6.18-rc1?

Chris: Mind taking a peek at this and seeing if someone could try to reproduce
it on an x455?
Comment 9 john stultz 2007-02-09 13:38:03 UTC

Comment 10 Jerry DeLisle 2007-03-04 12:36:21 UTC
I am getting a HWCLOCK failure with latest and updated FC6 installed on HP
Pavillion a1510y

I first noticed it in bootup and shutdown logs.  Then manually invoking hwclock
it is unable to read the clock.

What information do you need?
Comment 11 Jerry DeLisle 2007-03-04 15:43:26 UTC
Here is error message


# hwclock --show
select() to /dev/rtc to wait for clock tick timed out
Comment 12 Raj Thukral 2007-04-29 06:32:45 UTC
I have the same issue on my HP DV6110 running Fedora Core 6.  2.6.20-1.2933.fc6
and 2.6.20-1.2944.fc6  Let me know what other information you need.  The bug
seems to occur when the difference between the system clock and the hw clock is
high.  I typically had the system  hang on start up /  shut down occasssionaly
but when I was travelling i switched from EDT to PDT, then switch back to EDT
and now it happens every time I run hwclock --systohc.
Comment 13 Ingo Molnar 2007-11-18 07:53:59 UTC
2.6.24-rc3 includes a fix for the NTP code, related to hwclock and CMOS writes. Could you check whether this issue still occurs with that (or newer) kernels?
Comment 14 mereandor 2007-11-29 07:31:19 UTC
I have the same problem on a HP dv6155eu laptop. I also tested it with vanilla-sources-2.6.24_rc3.
The system freezes when I do a "hwclock --show" with or without --directisa.
Comment 15 mereandor 2007-11-30 03:45:41 UTC
So far I have tested this with the following kernel versions:
The freeze occurs in the following versions:
2.6.24_rc3 64bit (vanilla)
2.6.23 64bit (+tuxonice,notick,ck-patches,...)
2.6.22 32bit+64bit (kubuntu-7.10)
2.6.20 32bit (grml-1.0)
2.6.20 32bit (kubuntu-7.04)
2.6.20.11 64bit (grml64-0.1)

For my oldest Live-CD it seems to work:
2.6.16 32bit (grml-0.7)

I hope to be able to confirm that as soon as I'm able to compile a vanilla 2.6.16 kernel, and then work upwards until I find the first version that doesn't work.

once you are able to build kernels manually, you might want to try 
git-bisect - that should pinpoint the exact commit (out of 60,000 
commits) that broke this - with 10-20 kernel rebuilds (worst-case). If 
vanilla 2.6.16 indeed works then you can set the bisection up like this:

1)

install the 'git' package. (if you dont have it already.)

2)

clone Linus' latest tree. (if you dont have it already):

 git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-2.6.git

this will take some time to complete, but fetching the latest Linux 
source will be a lot faster as all subsequent pulls will be deltas. You 
can do it via:

 cd linux-2.6.git
 git-pull

that will fetch Linus'-tree-of-the-minute. It does not get any more 
bleeding edge than that. This is a fully functional Linux kernel tree 
which you can build just fine. All the git stuff is under 
linux-2.6.git/.git. If you patch your kernel and want to restore to the 
pristine git code just do:

 cd linux-2.6.git
 rm -rf *
 git-checkout .

3)

once you have the git tree, start bisection via:

 git-bisect start

build the kernel and check that it is a 'bad' kernel, and tell the 
bisector that it's a bad kernel:

 git-bisect bad

Tell the bisection engine that v2.6.16 is a "good" kernel:

 git-bisect good v2.6.16

at this point git-bisect will calculate a 'middle' commit and switches 
to it and checks the files out - build that kernel and test it. If it's 
"good", mark it such:

 git-bisect good

if it's "bad", tell the bisection engine about it:

 git-bisect bad

the number of commits will halve at every step - and eventually 
git-bisect will give you a single commit that introduces the breakage. 
Hopefully that commit will be something related to the RTC :-)
Comment 17 mereandor 2007-12-01 00:55:13 UTC

git-bisect bad b7408aff2d325581dcafffa5dbcc09c42ae64b5d

As the freeze does not occur on every call to hwclock I made a script that called it 200 times in a row. All revisions marked with good passed this test. All revisions marked as bad froze after 35 iterations maximum (most times it was below 5 times). I tested those failing after more than 25 iterations again and they failed earlier the next time.

I hope this helps.

does the lockup go away if you unapply the bad commit from the freshest 
tree? (i.e. from 'master', the 2.6.24-rc3-git6-ish kernel?)

you can extract the diff of the bad commit via:

  git-log -1 -p b7408aff2d32558 > bad.patch

and then do:

  patch -p1 -R < bad.patch

(-R is the 'revert' option.)

to apply the patch again, do:

 patch -p1 < bad.patch
Comment 19 mereandor 2007-12-01 01:35:11 UTC
It does not work when I unapply this commit. I didn't expect it to, since I don't use this LED driver or even have it enabled.
What should be the next step? Go back to the highest "good" revision and test it further so to confirm the result?
Comment 20 mereandor 2007-12-01 03:23:18 UTC
I just tried the last good version again and played around with git-diff a bit:

When I understand this the right way:
git-diff d9eaec9e295a84a80b663996d0489fcff3a1dca9 b7408aff2d325581dcafffa5dbcc09c42ae64b5d
should be the same diff that I get when I use git-log -1 -p b7408aff2d32558, as d9.. is the last working version and b74... is the first failing one. But the diff between the two is a huge thing not just the small patch that I get from git-log.
Comment 21 Ingo Molnar 2007-12-01 10:51:47 UTC
i've replayed your bisection log and it hones in on that LEDS commit, so 
believe one of the good/bad decisions was wrong. (or, the bug could be 
"spurious" or nondeterministic in some other way - but lets exclude that 
possibility for now because you managed to find a way to reproduce the 
lockup so well.)

to not have to redo the whole bisection, i'd suggest to replay up until 
the last "good" kernel, just paste these commands into a shell prompt:

 git-bisect start
 git-bisect bad e1cca7e8d484390169777b423a7fe46c7021fec1

 git-bisect good be967b7e2f7747a5ebf2a07ee627d9338491e784

NOTE: at this point it will suggest the d9eaec9e29 commit, but please 
double-check it whether it's indeed a "good" kernel. Continue from that 
point on and double-check every bisection point. Either this last 'good' 
decision, or one of the following 'bad' decisions could be wrong:

 905f14672e6d0552bfde954d5f7adb5f2c7a7960
 55c20c0af7fe7d5d09af4addfafcfe3bdc500f5d

 b7408aff2d325581dcafffa5dbcc09c42ae64b5d

it is not typical for a bisection to end with a series of 7 
'bad' bisection points - the chance for that is roughly 1/128. So 
somewhere around commits d9eaec9e295, 905f14672e or 55c20c0af7 you might 
have made a mistake.

If you still get the same result then we'll have to rethink the whole 
strategy - but i think the fact that it's 7 'bad' bisection points at 
the end strongly suggests an incorrect bisection point at one of the 
aforementioned points.

and this happens to me quite frequently too - even though i'm quite 
careful and experienced at it, roughly 1 out of 5 of my own bisections 
fails due to a bad decision. That's not a surprise: with 15 bisection 
points each, even a seemingly 5% failure/mistake rate multiplies up very 
quickly, to 1.05^15 == 2.05, a 50% total failure rate!

so i have automated certain types of bisections around the "git-bisect 
run" feature, but such automation cannot be universally applied to hard 
lockup bugs like yours.

"|" marks a reboot.
The numbers show how often "hwclock --show" was called successfully before the system froze
- 100 or above means that there was no hangup at all.
- -1 means that not even "setting system clock to hardware clock" worked

The method to extract a patch with git-log -p -1 d6454706c382ab74e2ecad7803c434cc6bd30343 didn't work for me this time, so I was unable to check if unapplying it from HEAD would help

I forgot to say that I started with good: [d9eaec9e295a84a80b663996d0489fcff3a1dca9] as it was the best tested version at this time.
Comment 24 Ingo Molnar 2007-12-02 07:14:19 UTC
btw., could you try to describe in what way the system freezes? Is it a hard hang - numlock led does not work, etc. - or a soft hang?
Comment 25 mereandor 2007-12-02 07:18:11 UTC
The system locks up completely: That means processor fan runs at full speed (after a few seconds) and there is no reaction to any user input, not even the LEDs for caps lock or num lock work.
Comment 26 Ingo Molnar 2007-12-02 07:31:05 UTC
d6454706c3 is a "merge commit" - an artificial commit that shows that someone (Linus, most of the time) has done manual merging. A merge commit is only metadata, it does not change the kernel source.

So somewhere along the line some commit was probably misidentified. Perhaps the method of identifying "good" kernels is inadequate?

Basically, every "bad" bisection point is 100% reliable (as long as you have not typoed it) - because if a kernel hung up even just one that means it's 100% bad. If a kernel passed 100 iterations that does not mean it's necessarily "good". (but it is a strong indicator)

I'm looking at the following two points right now:

 git-bisect good 24a77daf3d80bddcece044e6dc3675e427eef3f3
 git-bisect bad 19d1743315099665db4ce02c9942507a5ee1deea

and they _do_ seem plausible and narrow things down quite a bit. You can check the "suspected" commits via: "git-bisect visualize". This command will show you all the candidate commits that are still remaining between the last "good" and "bad" bisection points. There are a good deal of time code and architecture code related commits in that set of commits.

Could you check one of those bisection points (dc87c3985) manually, via:

 git-bisect start
 git-bisect good 24a77daf3d80bddcece044e6dc3675e427eef3f3
 git-bisect bad 19d1743315099665db4ce02c9942507a5ee1deea
 git-reset --hard dc87c3985e9b442c60994308a96f887579addc39
 git-checkout .

this gives you that commit, and after you have tested it you can do "git-bisect good" or "git-bisect bad" and you can continue with the bisection.

i picked this dc87c3985e commit from the visualized graph: it is one commit earlier than the stream of those "suspect" commits. So my guess would be that it's still a "good" kernel. One of the commits in the dc87c3985e..19d17433150 range could be the guilty commit.
Comment 27 Ingo Molnar 2007-12-02 07:35:15 UTC
Also, could you attach to this bugzilla the output file of the following script:

  http://people.redhat.com/mingo/cfs-scheduler/tools/cfs-debug-info.sh

best run it on a known "bad" kernel. (before the lockup) This script outputs a laundry list of system details so we'll have a good overview of what hardware environment this is.

also, could you attach the .config as well that you are using. (of a "bad" kernel, preferably.)

ok, that's good. Does the NMI watchdog work on your system? Add the 
nmi_watchdog=2 [or perhaps nmi_watchdog=1, if you system has an IO-APIC] 
boot option to the 'kernel' line of /etc/grub.conf. This feature will 
print a useful stack backtrace of hard lockups after 10-20 seconds, as 
long as you are on a text console. (or via serial if you have a serial 
console configured and attached via a null modem cable to another 
system.)

first make sure it works fine: boot into a known-bad kernel (preferably 
2.6.24-rcx) with nmi_watchdog=2 kernel boot option and check that the 
NMI count(s) in /proc/interrupts is increasing periodically. If they do 
it's OK and any hard lockup will hopefully be followed up by a useful 
stack dump printed by the kernel. Write the EIP line and the "Call 
Trace" lines down or make a digital picture of it.

if it does not work then you'll be met with a sad:

  NMI:          0          0   Non-maskable interrupts

output, or sometimes the NMI counts are stuck at a low count:

  NMI:       1200       1230   Non-maskable interrupts

and dont increase. In this case the hard lockup wont be detected by the 
NMI.

config-2.6.24_rc3

I attached the debug information and the kernel config - both for the 2.6.24_rc3 kernel.

I didn't get the NMI Watchdog thing to work, but it still may be a configuration issue. I just activated the watchdog software driver.
with nmi_watchdog=1 it gets stuck at low numbers; with 2 it's at 0
I hope you can help me with this.

I tried the revision you proposed and it showed that the freeze is less reproducible than I thought: First it got stuck at the first test and then it passed 100 two times in a row. So I guess there is no point in bisecting anymore.

i think your bisection results so far are excellent and have narrowed 
down the bug quite a bit. Bisection is still a powerful tool even if a 
hang is nondeterministic to reproduce, because we can definitely 
identify 'bad' commits.

could you try to run a really long test for commit 24a77daf3d80bd, so 
that we establish that it's a 100% "good" kernel? That way we know that 
it's one of the 36 commits in that range. Between 2.6.16 and 2.6.24-rc3 
there are 53317 commits (!), so we've come quite a long way. Those 36 
commits definitely look "suspect" in the sense that they change 
hardware-relevant code on x86.
Comment 32 Ingo Molnar 2007-12-02 11:48:59 UTC
i found this in the boot log:

| Nvidia board detected. Ignoring ACPI timer override.
| If you got timer trouble try acpi_use_timer_override

not that it should make much of a difference, but might be worth trying: 
add acpi_use_timer_override to the boot options.

for some reason the NMIs are not coming - this is not your fault.

does it get any better if you boot with the idle=poll option? Sometimes 
this makes nmi_watchdog=2 work better. (because the CPU does not enter 
C2 mode)
Comment 34 mereandor 2007-12-02 12:28:21 UTC
I made a script that randomly calls: "hwclock --(show|systohc|hctosys)( --directisa)?"
This makes 24a77daf3d80bd freeze after less than 100 iterations.
So it seems that it is not a good kernel after all.

I'm now running the same script with the 2.6.16 based LiveCD (grml-0.7 i386). It is now at ~700 iterations.

Btw. the earliest kernel I am able to run from the git-repository is around the 2.6.17 release. Earlier kernels don't seem to include the nvidia SATA driver that I need to access the hard drive. At least not for x86_64.

The idle=poll thing did indeed fix the issue with NMI so I will try to get the first "screenshot".

With acpi_use_timer_override it is now at 150 on 24a77daf3d80bd. I'm going to try it now with 2.6.24_rc3.
Comment 35 mereandor 2007-12-02 12:37:36 UTC
2.6.24_rc3 still hangs after a few iterations, but NMI seems to have no effect.
The counter in /proc/interrupts increases, but I'm not getting any debug information when the system freezes.

simulate a hard lockup

Could you try the attached lockupcli.c code, does the NMI watchdog print anything, or does it lock up silently?

You have to be on a VGA text console to see NMI watchdog output normally. (run lockupcli from there too)

normally you should get a 'NMI watchdog lockup detected' type of message within a minute after experiencing the hard lockup.

If you get it in lockupcli, but the hwclock lockup does _not_ get detected by the NMI watchdog, then this is possibly some deep, hardware level lockup (locked up system bus or something) so that there is no real CPU activity anymore. (and no NMIs)

In that case the only real debug tool would be bisection - which will be pretty hard if the last testable 2.6.17-ish git kernel still locks up for you ...
Comment 37 mereandor 2007-12-02 13:10:35 UTC
I have never used the VGA text console only the framebuffer console, so this would be the reason why I don't get any watchdog output.
Could you please point me to a relevant documentation about how to get to a VGA console?

hm, i _think_ the framebuffer console should be able to be printed to 
from the NMI watchdog as well - but generally it's a bit more fragile.  
Do you get NMI watchdog output from lockupcli? If not then the problem 
is likely the fbcon that is preventing it from being printed.

I started with vga=ask now and chose a VGA mode. Now I'm getting output from watchdog when I run lockupcli. The problem is: I'm still not getting anything after a hwclock freeze.

ok, this suggests some "harder than hard lockup" wedge of the system :-/

does that 2.6.17-ish kernel (which has the required SATA driver you 
need) lock up too? If yes then there's no good way to bisect this i 
suspect. If yes then bisection might be a workable (albeit very hard) 
option still.

if you are on a vga console, then could you try to run "strace hwclock 
--show" in a loop, and see which is the last line you get before it 
locks up? It will likely lock up in an ioctl(4) [that is where hwclock 
calls the kernel's RTC driver] - could you write down that exact ioctl 
line? (and attach the output of "strace -o strace.log hwlock --show" of 
a non-locked-up instance of hwclock, for comparison)
Comment 41 mereandor 2007-12-02 13:50:23 UTC
It's time to sleep for today so I will continue tomorrow. I will provide you with the strace output.

Another thought is: The LiveCD has a 2.6.16 i386 kernel obviously _with_ the neede d driver, and it's working there (hopefully 700 iterations with my shiny new hwclock torture script are enough). So in the worst case I could set up a 32bit system and continue bisecting there. How can I find out with which revision nv_sata was added for x86/x86_64?

hm, in theory such drivers are available to all platforms at once. And 
often "support" means the introduction of relatively small amount of 
code, so i couldnt tell it right away. Vanilla 2.6.16 x86_64 definitely 
didnt work for you?

"git-log --follow drivers/ata/sata_nv.c" shows a really long history 
going back to 2.6.12-rc2, when git history started. Perhaps what broke 
x86_64 for you was some subtle .config change that resulted in the 
disabling of the driver?
Comment 43 mereandor 2007-12-03 04:16:10 UTC
Created attachment 13836 [details]
strace-hwclock.log

I attached the strace output for a normal run of hwclock --show.

When it freezes the last lines look like this:
ioctl(3, RTC_RD_TIME, {tm_sec=2, tm_min=59, tm_hour=12, tm_mday=1, tm_mon=11, tm_year=107, ...}) = 0
... a screen full of identical ioctl calls ....
ioctl(3, RTC_RD_TIME, {tm_sec=2, tm_min=59, tm_hour=12, tm_mday=1, tm_mon=11, tm_year=107, ...}) = 0
ioctl(3, RTC_RD_TIME

The last line is cut after RTC_RD_TIME and before the comma.

With early kernels the problem was that the option in menuconfig (and make oldconfig was unable to assign the symbol)  simply vanished (other drivers in the same category are still there). I'm going to try to configure a 2.6.16 kernel again today.
Comment 44 Ingo Molnar 2007-12-03 04:53:03 UTC
> The last line is cut after RTC_RD_TIME and before the comma.

ok, that narrows down the lockup site quite a bit - the likely source is 
the rtc_get_rtc_time() function.

if you do:

  git-blame drivers/char/rtc.c

and search for rtc_get_rtc_time then you can see how various commits 
affected this particular function.

much of this function stayed unchanged since 2.6.12, which eases 
analysis. So excluding the 1da177e commit, the following commits 
affected this function directly:

  0f749646
  358333a0
  403fe5ae
  47f176fd
  b7599587

i got this list of commits via:

   grep -v 1da177e rtc_get_rtc_time.c | cut -d' ' -f1 | sort  | uniq

( where rtc_get_rtc_time.c is a new file i created by pasting the 
  rtc_get_rtc_time portion of the git-blame output. Someone should 
  extend git-log/git-blame to filter down to the function level. )

here's an analysis of those commits:

- commit 358333a0 is a pretty harmless cleanup of commit 403fe5ae.

- commit 0f749646 i'd exclude as a candidate bad patch. (primarily 
  because i wrote it and i always write perfect code, secondarily 
  because this cannot affect an ioctl level call.)

- commit 47f176fd looks harmless too. (not the least because it was
  Acked-by me. It introduced also a bug that 403fe5ae then fixes. I did
  not ack that bug, of course.)

- commit 403fe5ae could be bad in theory - it changes an msleep() to
  a jiffies based loop.

- commit b7599587 is something that could be suspect too: it reads a new
  CMOS register that was never read before. This got introduced in the
  2.6.16 timeframe, so it roghly lines up with your timeline of the 
  breakage.

so i think we've narrowed it down to two commits that changed this 
function. (and of course any indirect change could affect this function 
as well, so these 2 commits are not necessarily a given as the source of 
your regression)

to undo commit b7599587 (for testing purposes) on a recent kernel i'd 
suggest you edit drivers/char/rtc.c and change the following line:

   rtc_tm->tm_wday = CMOS_READ(RTC_DAY_OF_WEEK);

to:

   rtc_tm->tm_wday = 0;

this avoids the new CMOS read quite efficiently.

to undo commit 403fe5ae (for testing purposes) i'd suggest you just 
change this code:

        while (rtc_is_updating() != 0 && jiffies - uip_watchdog < 2*HZ/100)
                cpu_relax();

to:

        while (rtc_is_updating() != 0 && jiffies - uip_watchdog < 2*HZ/100)
                mdelay(20);

perhaps a too frequent polling of the RTC_FREQ_SELECT register of your 
CMOS wedges the hardware? If i were forced to pick one commit only i'd 
guess this latter one as the source of the regression.
Comment 45 mereandor 2007-12-03 04:55:18 UTC
I forgot to say that the log was generated on 2.6.24_rc3.

I got the 2.6.16 kernel to compile, but I had to use a makefile patch to get rid of:
ld: i386:x86-64 architecture of input file `arch/x86_64/boot/compressed/head.o' is incompatible with i386 output

I'm now beginning to test 2.6.16 and when it's "good" I will start bisecting again taking 2x1000 iterations of the new test script separated by a reboot as good.
Comment 46 mereandor 2007-12-03 05:22:06 UTC
When I run the tests on 2.6.16 I observed another thing by chance:
The test itself runs perfectly (not a single freeze) but switching to another console via (strg+alt+f2) almost immediately produces a freeze, after the new console is displayed.
And now yet another: After stopping the tests I used ntpdate to get the right time again (somehow the tests lead to ~2 days getting lost ~166000s offset). After that doing a hwclock --systohc leads to a lock up.

This is all with v2.6.16. Both things worked fine when I tried to reproduce this with the LiveCD.
I didn't catch this things before because they wouldn't show up if I didn't use --systohc.

hm. Does it get any better if you replace the rtc_is_updating() line in 
rtc_get_rtc_time() with a brute-force mdelay(100) line?

also, can you still reproduce the lockup if you use only a single core, 
i.e. if you boot with maxcpus=1 ?
Comment 51 mereandor 2007-12-03 10:14:12 UTC
To replace rtc_get_rtc_time() did not make a difference, but setting maxcpus=1 after that did. It now seems to run fine, even with the extended version of my testscript and even when switching to another terminal. The next thing I try is to undo the changes to rtc.c and then try again with maxcpus=1 I guess.
Comment 52 mereandor 2007-12-03 10:42:12 UTC
I can confirm now that 2.6.24_rc3 works well with maxcpus=1.
Comment 53 Ingo Molnar 2007-12-03 14:00:09 UTC
> I can confirm now that 2.6.24_rc3 works well with maxcpus=1.

ok, that's quite a clue. Could you try the following experiment: boot 
with maxcpus=2 [i.e. both cores active], but restrict the _test-script_ 
itself to CPU#0, via binding the shell from which you start it to CPU#0:

   taskset -p 01 $$

all commands you start after this will be bound to CPU#0.

(the RTC/CMOS might still be accessed from another CPU, by the timer 
interrupt for example - but perhaps the key is to do all of the hwclock 
CMOS accesses from CPU#0.)
Comment 54 Ingo Molnar 2007-12-03 14:21:49 UTC
another thing, could you enable the following options in your .config 
(on 2.6.24-rc-latest):

 CONFIG_DEBUG_KERNEL=y
 CONFIG_PROVE_LOCKING=y

and see whether you get any extra debug messages before the lockup 
happens?
Comment 55 mereandor 2007-12-03 23:17:03 UTC

ok, just wanted to make sure we dont miss something obvious. 
(framebuffer console is fine as long as you made at least one successful 
hwclock command invocation before getting any lockup.)
Comment 58 Ingo Molnar 2007-12-04 01:55:42 UTC
> taskset does not help with maxcpus=2 -> It froze at the first call of

could you try to redirect the RTC interrupt and IRQ0 to CPU#0? You can 
configure it via /proc/irq/8/smp_affinity and /proc/irq/0/smp_affinity. 
They default to 00000003. (it's an affinity bitmask - the bits for CPU#0 
and CPU#1 are set.) To bind it to CPU#0, set it to 00000001.

this way we should have all concievable RTC related activities on CPU0, 
and we should have the same/similar access patterns as you got with 
maxcpus=1. In theory.

in your current log the interrupts are well-spread out:

           CPU0       CPU1
  0:         75      23663   IO-APIC-edge      timer

so maybe the lockup is related to getting an RTC interrupt (or IRQ#0) on 
CPU#1 while the CMOS access is ongoing on CPU#0 - or something like 
this.
Comment 59 mereandor 2007-12-04 02:34:16 UTC
> as long as you made at least one successful hwclock command
I didn't. Simply because I wasn't able to make even _one_ successful call to hwclock --show  since I set maxcpus=2 again.

Restricting the irqs does not seem to work properly:
With irq8 there is no problem, but when I do:
echo 1 > /proc/irq/0/smp_affinity
I get: write error: Input/output error

Restricting irq8 alone did not work.
Comment 60 mereandor 2007-12-04 02:36:07 UTC

ok. i forgot that we disallow the restricting of IRQ0.

if you temporarily disable the "irqbalance" service via ntsysv and 
reboot, do all IRQs end up on CPU#0? (you have CONFIG_IRQBALANCE 
disabled, so they should end up there)

so once all IRQs are on CPU#0, does the lockup go away?

hm, this might still allow the hw to balance interrupts.

you couldnt set IRQ#0's mask due to the "IRQF_NOBALANCING" flag in 
arch/x86/kernel/time_64.c's 'struct irqaction irq0' initializer. (around 
line 100) Could you remove it from there, and can you set 
/proc/irq/0/smp_affinity with that change in place?

or if you run the 32-bit kernel, the IRQF_NOBALANCING flag is in 
arch/x86/mach-default/setup.c, around line 186.

(i suspect one of the lines was for IRQ#8, right?)

> Even when I add taskset -01 $$ in front of those commands it freezes.

that's weird. To make it even more sure that absolutely nothing runs on 
CPU#1, could you try to boot via init=/bin/bash, that will make bash the 
init task and nothing else runs. (and no consoles, no nothing) Then 
please bind everything to CPU#0 and try to get it to lock up. (Warning: 
if you boot like this then Ctrl-C might not work - so only run commands 
that you know will finish within a finite amount of time.)

also, for good measure, could you bind all interrupts to CPU#0, via:

 for N in /proc/irq/*/smp_affinity; do echo 01 > $N; done

with all these measures in place i cannot think of anything else that 
would run on the second core and that would/could somehow affect the 
southbridge/CMOS.
Comment 65 mereandor 2007-12-04 11:25:11 UTC
It seems that taskset + setting all interrupts to smp_affinity=1 did the job already. I will double check this now without taskset and again with only irq0 and irq8 set to smp_affinity=1.
Comment 66 mereandor 2007-12-04 11:33:57 UTC
I don't need taskset to eliminate the freeze, but it seems that I need to restrict an irq above 10 to succeed. I try now to determine all irqs that matter.
Comment 67 mereandor 2007-12-04 13:08:27 UTC
Determining the irqs seems to be more difficult than I thought. When I make irq23 (nv_sata) able to use both cpus this does not matter until there is disk i/o.
I could run hwclock --show 100 times, but when I did a "du -sh /" in another terminal it froze within a second.

The disk i/o does not matter when irq23 is restricted.
Comment 68 mereandor 2007-12-04 13:51:45 UTC
Hm, for now this is all I can get reliably:
It never failed with taskset and all irqs restricted.
I did modify my init scripts to run taskset and your for loop before hwclock is called. It froze several times since then, but this may be due to me lacking bash knowledge.
When I activate irqs it sometimes freezes and sometimes not. When it freezes then at the first call to hwclock --show after a modification to the restrictions. 

Except the observation above there is nothing reliable.
Comment 69 mereandor 2007-12-07 04:25:43 UTC
I was just reminded of my first attempt to solve this bug: After some research on the internet I suspected acpi to be responsible for the freezes. I just tried to switch acpi=off with 2.6.24_rc3 and indeed the freeze did not occur.

So there are now 2 possibilities to eliminate the freeze:
1. taskset -p 01 $$ + for N in /proc/irq/*/smp_affinity; do echo 01 > $N; done
2. setting acpi=off as a kernel parameter

hm. Do you still have two cores after acpi=off? And are all irqs going 
to both CPUs in that case? If not then acpi=off might just be a superset 
of the affinity setting.

3. setting maxcpus=1
Comment 72 mereandor 2007-12-07 04:38:39 UTC
With acpi=off there are still two processors, but both seem to get the id 0. (/proc/cpuinfo says "processor: 0" two times). So no luck there.

Is there anything else that I can test?
Comment 73 mereandor 2007-12-07 06:36:40 UTC
I now made a script that:
1. randomly chooses an interrupt
2. sets all other interrupts to smp_affinty=1
3. sets chosen interrupt to smp_affinity=3
4. runs 20 random hwclock commands
5. starts again at 1. as long as it doesn't freeze 

The table below shows how often an interrupt was tested and with what interrupt the test froze.

IRQ| test series
0 : 0 0 2 0 2
1 : 0 0 1 0 2
2 : 0 0 2 0 0
3 : 1 0 2 0 2
4 : 2 0 1 0 0
5 : 2 0 1 0 0
6 : 1 0 1 1 1
7 : 2 0 1 0 0
8 : 0 0 5 0 1
9 : 1 0 3 0 1
10: 1 0 2 1 0
11: 4 0 0 0 1
12: 2 0 2 0 0
13: 3 1 0 0 1
14: 2 0 2 0 3
15: 2 0 1 0 2
18: 1 0 3 0 0
19: 0 f f f 1
20: 0 0 1 0 0
21: 0 0 1 0 1
23: f 0 1 0 f

The digits are the numbers of times it was tested "good". f means it failed during the test for this IRQ.

Since 19 is eth0 and it failed so often, I made the fifth test with "ifconfig eth0 down" and it seems it helped.

My current hypothesis is that it does not depend on the special IRQ, but it freezes as soon as there is any interrupt handled by CPU#1.
In my case this would naturally be the ethernet card and the disk. After shutting eth0 down the next run with it unbound was successful (fifth column).

hm. So a possibly safe method of reading the CMOS on your box would be 
to first turn off irqs on all CPUs, then read the CMOS register, then 
re-enable interrupts again? arch/x86/kernel/cpu/mtrr/main.c has such 
code (the ipi_handler() stuff).

ouch! Could you post the full dmesg form such an acpi=off bootup? 
(please also add apic=verbose so that we get all the details)
Comment 76 mereandor 2007-12-07 08:12:05 UTC
I just saw that the cpuinfo is the same when I do a normal start. The 2 CPUs differ in the core_id field so everything seems alright. I've just never seen it since even a core2 processor is recognized with two different processor ids. It seems to be different for an athlon X2.

I can upload the dmesg-output though, if you are still interested.

For the other thing. I don't quite get what you mean. My insights into kernel hacking end somewhere near applying patches ...

my guess would be hardware defect or BIOS upgrade needed. We might be 
able to work it around by taking the ioapic_lock when doing CMOS ops - 
but this definitely does not have the appearance of a real kernel bug - 
it triggers very easily on your box and does not seem to trigger on 
other boxes.

I'll try to update the BIOS. The only thing is: This doesn't seem to be a problem with WinXP so it would be hard to get it repaired.

It's a "shot in the dark" workaround attempt, serializing IO-APIC accesses and RTC accesses.

Thanks for the patch! I will try it as soon as possible.

Since I still have a warranty for this laptop I will try my luck with HP. It really seems to be a hardware defect:
- There is probably more than one laptop around that has this motherboard/cpu combination and is running linux just fine.
- Also such hardware limitations do not seem sane for a dual-core system.

Thanks very much for taking time to guide me through testing this out. ;)
Comment 83 Ingo Molnar 2007-12-10 01:38:14 UTC
> Thanks for the patch! I will try it as soon as possible.

it's really just a partial attempt: the workaround only excludes IO-APIC 
sequences - there are other side-effects of executing interrupts on 
another core that this does not impact. The only truly reliable way of 
getting rid of all side-effects is to bind all irqs to the first core - 
but that is not a reasonable limitation for a general purpose OS (of 
course). In the patch i also reduced the polling frequency of the 
is_rtc_updating() call. Which btw. seems a bit buggy to me:

        while (rtc_is_updating() != 0 && jiffies - uip_watchdog < 2*HZ/100)
                mdelay(1);
        ...
        spin_lock_irqsave(&rtc_lock, flags);

i'm not quite sure what rtc_is_updating() is supposed to do - it does 
this:

        uip = (CMOS_READ(RTC_FREQ_SELECT) & RTC_UIP);

if this is a "you must not read the CMOS when the RTC_UIP bit is set" 
restrictition then the current Linux code that uses this bit is buggy. 
There's a (relatively low) chance that your lockup is related to that. 
I'll do a second patch too that also solves this issue. But we've had 
this slightly racy way of testing for RTC_UIP for ages, so i doubt it 
can cause _that_ many problems. we'll see.

i think the chance for that to be related to the lockup is zero: the 
CMOS updates itself once per second (it is a persistent, battery-backed, 
seconds granularity clock), and the UIP (Update In Progress) bit is set 
when such an update occurs. But an interrupt on another core has no CMOS 
side-effects at all.

RTC test patch

Please try this patch (rtc-hack-2.patch) too.

this turns off all CMOS accesses within the rtc_get_rtc_time() function. This breaks hwclock in that an incorrect date will be returned - but it should allow us to test the theory that these CMOS accesses are the ones that are causing the lockup.

lets try this to make sure we are on the right track.

ok. Lets forget about this patch then and try the second patch, just to 
reassure ourselves that it's indeed those CMOS_READ sequences that cause 
the lockup.
Comment 88 Ingo Molnar 2007-12-10 02:03:21 UTC
i noticed this in your bootlog:

  AMD Turion(tm) 64 X2 Mobile Technology TL-52 stepping 02
  Brought up 2 CPUs
  testing NMI watchdog ... OK.

While i asked you to enable it to get a debug dump from the wedged 
system, i'd now suggest to turn off the NMI watchdog, to make sure it 
does not interact. The NMI code makes CMOS accesses in certain 
circumstances.

In the meanwhile I tried whether updating to the newest BIOS version helps, but it did not.

The freeze still occurs with both patches applied (workaround+test). (A make clean should suffice to guarantee that the patch is applied in the binary too, doesn't it).

I have to make a break with testing now. But I will test this again soon to be sure that I didn't make any mistakes.

yeah, make clean is more than enough. (usually make will pick up any 
changed source files and rebuild any dependencies)

does hwclock --show return some weird date? That should make sure that 
the test patch is applied too.

to make sure that rtc_get_rtc_time() has no effect, could you edit 
drivers/char/rtc.c's rtc_get_rtc_time() function and add this line to 
the 6th line of it:

	return;

(i.e. return early from this function without doing anything)
Comment 91 Ingo Molnar 2007-12-10 02:29:16 UTC
> (i.e. return early from this function without doing anything)

if with this hack it's still locking up then please repeat the strace 
experiment to figure out in which ioctl it is locking up.
Comment 92 mereandor 2007-12-10 05:52:47 UTC
So now it gets strange:
I checked 3 times that the patches are applied, but the clock still gave the right time. Then I checked the kernel configuration and saw that HPET was activated. First i tried to deactivate RTC (and only have HPET) with the result that hwclock didn't find /dev/rtc anymore. Then I deactivated HPET completely and activated RTC again (now built-in not as module) and now the patch seems to do its work.

With the hack applied I'm unable to boot properly because hwclock waits until a second passes, but with your patch it never does. So it's stuck in an endless loop.

I unapplied the second patch then and tried it only with the first patch applied this way and it still froze.
Comment 93 mereandor 2007-12-10 06:14:09 UTC
I just did another test: To reassure myself that this is not caused by a broken toolchain, I recompiled the kernel with a LiveCD and the result is the same. So it's unlikely that this is caused by the toolchain.
What else would I have to test to cancel out everything except the kernel and the hardware as a cause?
Comment 94 David P. Reed 2007-12-13 18:50:35 UTC
See bug 9511. This should be the same problem.
Comment 95 Ingo Molnar 2007-12-14 04:57:45 UTC
> See bug 9511. This should be the same problem.

oh my gosh! Indeed:

   ------- Comment #10 From David P. Reed 2007-12-13 18:49:04 -------
   On my AMD64x2 machine, I discovered the cause is the "outb" to port 
   0x80 done in the inb_p calls used in the CMOS_READ and CMOS_WRITE 
   macros.

could you just try the following, remove this line from 
include/asm-x86/io_32.h and include/asm-x86/io_64.h:

        asm volatile("outb %%al,$0x80" : : : "memory");

does that give you a non-freezing hwclock?

x86 IO delay fix

Could you try this patch? It replaces port 0x80 access with an udelay(1).

Updated patch - this one is against the upstream 2.6.24-rc-ish kernel. (previous ones were against x86.git)
Comment 99 mereandor 2007-12-14 08:12:24 UTC
I sent the laptop back for repairs as I am pretty sure that it the freezes are at least partially hardware related. Two days ago it froze a few times during different tasks (ie. once when running windows ...).
So it will take 4-6 weeks until I can try the new kernel patch.
Comment 100 Ingo Molnar 2007-12-17 14:28:31 UTC
We suspect that the hwclock lockups are related to the port 80 access related problem debugged by David P. Reed & co on lkml. (see the "[PATCH] x86_64: fix problems due to use of "outb" to port 80 on some AMD64x2 laptops, etc." thread and other related threads)

Please attach the output of dmidecode so that we can add the boot-time workaround for this problem.

x86: IO delay quirk

Please apply the attached patch to 2.6.24-rc5 and boot with the new io_delay=0xed boot option - does it resolve the problem? (using the DMI info we can make this boot selection automatic)

dmidecode output

Good morning!

I tested the patch with 2.6.24-rc5 and it seems to work. I enabled the io_delay=0xed option in .config, so the bug is gone with and without the boot-parameter.
I attached the dmidecode output for my laptop.

Does this patch also apply to newer rc-releases?

Keep up the great work!
Comment 104 Natalie Protasevich 2008-03-20 00:44:19 UTC
It looks like the patch has been committed, so the bug can be closed.
Thanks.
Comment 105 Ingo Molnar 2008-03-21 02:21:21 UTC
yes, we pushed this category of fixes upstream, via:

  commit b02aae9cf52956dfe1bec73f77f81a3d05d3902b
  Author: Rene Herman <rene.herman@gmail.com>
  Date:   Wed Jan 30 13:30:05 2008 +0100

      x86: provide a DMI based port 0x80 I/O delay override.

and subsequent patches. We can still add more DMI quirks if dmidecode is 
reported to this bugzilla. I just added the one reported by 
mereandor@gmail.com.
