patch to revert PCI race fix
Test if irq's got enabled early, barf about it, and disable them again Detect if parsing parameters enables irq, and notify that. Prevent a down-read in pci_find_subsys when the pci device list is empty. |

Can you boot with earlyprintk=vga (or better earlyprintk=serial,ttyS0,baudrate if you have a serial console) and show the full output of that? There are output from kernel with enabled 'earlyprintk' option.

<0>Kernel panic - not syncing: Attempted to kill the idle task!
Hmm, your kernel GPs on this instruction 0: 65 48 8b 04 25 10 00 mov %gs:0x10,%rax This could only happen when %gs points to a non canonical address or the GS register is totally broken. But the base looks ok and index is 0 so no rpl/limit etc violation possible. GS:ffffffff803c0000(0000) As far as I can see the oops is impossible (or at least outside the architecture). None of the possible #GP sources for MOV apply Do you get the same oops when you boot multiple times? When you go back to the old kernel does it work again? My HP Pavilion zv5452ea suffers the same problem. I'll try to boot with earlyprintk as soon as I can. The problem still exists with 2.6.19-rc6 $ cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 4 model name : AMD Athlon(tm) 64 Processor 3000+ stepping : 8 cpu MHz : 800.000 cache size : 1024 KB fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow bogomips : 1596.38 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp $ ./ver_linux If some fields are empty or look unusual you may have an old version.

It's impossible but it does every time. I'm doing a git bisection and it still does the same error on bad bisect. I haven't finished yet. I think it's something related to x86_64 since a very similar 32bit linux installation works fine.

I tried to revert the commit:

patch to revert PCI race fix
Here's a patch to revert the commit mentioned above, which should apply to
2.6.19 and newer. Please confirm that reverting this patch solves the problem.
That should have been "Please confirm that *applying* this patch solves the problem" Downstream report at http://bugs.gentoo.org/157693 OK, fixed. bugme-daemon@bugzilla.kernel.org writes: > http://bugzilla.kernel.org/show_bug.cgi?id=7505 > > ------- Additional Comments From agalanin@mera.ru 2006-12-18 07:39 ------- > OK, fixed. Greg. It appears commit d71374dafbba7ec3f67371d3b7e9f6310a588808 which replaced the pci bus spinlock with a semaphore causes some systems not to boot. I haven't a clue why. So I figure I would toss the ball over to your court to see if you can look and see what needs to happen to resolve this problem. There appears to be at least one positive confirmation that reverting this patch allows this patch fixes the problems. Eric Hi, We got the exact same results on a tyan-s2891 motherboard with dual opterons. We have two types of S2891 of which one type fails to boot 2.6.18 and higher, but the other type happily runs 2.6.19. We have flashed the bios up and down on both systems, but that really doesn't help: 1 type works, and the other type panics. The only difference I can find is that the working versions are purchased later so maybe the motherboard revision is different. With the patch applied we can boot 2.6.19 happily on the servers that paniced before. > There appears to be at least one positive confirmation that reverting > this patch allows this patch fixes the problems. > > Eric Hello.

We shouldn't have touched pci_bus_lock that early? Perhaps acpi does PCI things very early.. Conceivably an accidental early local_irq_enable could cause bad things, but that rwsem should be 100% uncontended. Could the reporters please determine whether disabling the various CONFIG_DEBUG_* options prevents this? Such as CONFIG_DEBUG_LOCKDEP, CONFIG_DEBUG_LOCK_ALLOC, CONFIG_PROVE_LOCKING, etc? Also, some additional oops traces would be nice, if we can get them. (Please do reply-to-all via email from now on, rather than using the bugzilla UI).

But it seems interrupts are on--look at the flags:

Just diving into the sources.
Is that something like:
if(!raw_irqs_disabled_flags) printk "irqs are enabled";
(At that moment it might have crashed already.. :-)).
I don't see the complete context yet, but I hope the irq is
triggered after the irq is somehow enabled.
BTW: the panic occurs on half of my boards on tyan S2891 with 2
opterons, of which the only difference seems to be the purchase
date (and hence probably the motherboard revisions). (Haven't got
time yet to pull them out of the rack and compare the
motherboards).

Somehow ide_setup is enabling irq's at that time. We have these parameters already for a long time, and it seems *that's* the difference between the series that were bought later: somebody removed that from the kernel command line, and so allowed them to boot. Can others confirm that this is a problem in the ide_setup that somehow enables irq's in the early phase? (In other words: will your system also crash when using hdb=noprobe and such?).

Without proof^H^H^H^H^Hpasting my dmesg and the "diff", I already
concluded that ide_setup was the culprit. (I've debuged
parse_one, and it barfed around the 3rd parameter which is
hdb=noprobe).
Anyway, a bad night of sleep reminds me that our EM64T boxes also
have this line (which actually is a remainder of our VA1220 boxes
;-) ), and they don't barf, so it must be either the combination
of the sata_nv together with the pata driver part, *or* just the
pata driver part. (Our opteron != nforce chipsets also works).
I will trace down the ide_setup today. First loads of coffee.

Applied to 2.6.19 it doesn't change anything. It still panics.
How can I have something similar to a serial console on a laptop without
serial port but with a parallel one? Will netconsole work?

I've already tested that (as I said somewhere in the bugzilla so
it probably got lost somehow :-) ): It doesn't solve the booting
problem, and I really don't have an idea what it does, nor does
it output any debug code. So I left it at: doesn't fix ;-).
Anyway: on to the ide_setup tracking....
(I've noticed that the notifier of this problem als has idebus=66
or something similar, so that explains in his case the
early call to ide_setup.)

I can't take any digital photo. Well I got this:
2.6.19 + lib/rwsem-spinlock.c patched + hdc=ide-cd or idebus=66 >> panic
2.6.19 + lib/rwsem-spinlock.c patched + no ide_setup calls >> works!!!

Aaarrgh...
Somewhere between the call to ide_setup and ide_init_hwif_ports
the interrupts get enabled. But I haven't got to the point where
exactly...

So as I read it: init_hwif_default calls ide_init_hwif_ports with irq's
disabled, but upon entrance, the irq's are enabled.
That really makes no sense to me.
So I will continue digging this code (there must be something recursive going
on).

------------------------------------------^^^^^^^^^^^^^^^^^^^^^^^^^^^
which does a if (pci_find_device(PCI_ANY_ID, PCI_ANY_ID,

will: down_read(&pci_bus_sem);
also enable interrupts?
Since that is called:
init/main.c start_kernel
kernel/params.c parse_args("Booting kernel"
kernel/params.c parse_one

I've altered your patch to do the spin_lock_irqsave in down_read.
I am very ignorant and stupid. That's why I am doing it without
thinking why or why not de irqsave is ok in that region or not.
And the results are:
include/asm-i386/ide.h ide_default_io_base(): blaat: interrupts were disabled@49
include/asm-i386/ide.h ide_default_io_base(): blaat: interrupts were disabled@51
include/asm-i386/ide.h ide_default_io_base(): blaat: interrupts were disabled@59
Meaning: it works.
Repeating: I am very stupid, so I don't know if saving the irq state is ok or
not in down_read.

The Andrew Morton patch but the rewritten for down_read makes the
symptoms go away.
The problem obviously is that the ide_setup pokes the pci
subsystem way too early.
Parsing of the ide parameters should be delayed until the next
run of parse_args I guess.

I can confirm this is a *GENERIC* X86_64 problem:
----
Kernel command line: console=tty0 console=ttyS0,115200 hdb=noprobe root=/dev/md0
init/main.c start_kernel(): interrupts were disabled@525
ide_setup: hdb=noprobe
init/main.c start_kernel(): interrupts were enabled@529
...
start_kernel(): bug: interrupts were enabled early
----
This is on a dell 1950 with a core 2 duo processors.
You have to have ide compiled in, and set ide options to get the irq's enabled,
and then have a setup which will have an irq pending before the irq controller
get's initialized to get the panic. The dell1950 does not panic, the kernel
merely warns.
I am pretty sure the i386 tree has the same problem but I haven't checked yet.
Anyway: the panic is just a way of noticing. The bug is that irq's are enabled
before the irq controller is set up.
But to make the ide_setup/irq bug go away, I think it might be an acceptable
solution to just disable the irq's again after the parse_args, and just to wait
until the SATA tree takes over the IDE tree.

A very similar i386 linux installation works fine on my laptop, but that
i386 kernel never had problem.

The question is not if the kernel panics, the question is if irq's get enabled too early. As we can see at the number of reports, only a handful panics, but I've seen all our core 2 systems all have the same problem, and could therefore in special cases panic during boot. I think the other patch just to check if irq's get enabled will should also be included (and subsequentially should disable it until the real problem is solved). Regards, Ard Could someone please test this? From: Andrew Morton <akpm@osdl.org> Various people have reported machines failing to boot since pci_bus_sem was switched from a spinlock to an rwsem. The reason for this is that these people had "ide=" on the kernel commandline, and ide_setup() can end up calling PCI functions which do down_read(&pci_bus_sem). Ard has worked out the call tree: init/main.c start_kernel kernel/params.c parse_args("Booting kernel" kernel/params.c parse_one drivers/ide/ide.c ide_setup drivers/ide/ide.c init_ide_data drivers/ide/ide.c init_hwif_default include/asm-i386/ide.h ide_default_io_base(index) drivers/pci/search.c pci_find_device drivers/pci/search.c pci_find_subsys down_read(&pci_bus_sem); down_read() will unconditionally enable interrupts and some early interrupt (source unknown) comes in and whacks the machine, apparently because the LDT isn't set up yet.

Preliminary patches:
- pci fix of Andrews patches
- parse-one detection of Yanmin
- start_kernel detection and workaround (disable them again)
These are the patches that I am about to test in the next 2
hours... :-)
Anyway: I think it is possible that other drivers are also
potential irq enablers as soon as they are called from parse_one.
Usually I compile network drivers as modules, but in diskless
setups this might not be the case :-).

As said: it was doing a callback to obsolete_...
This replaces the patch into not being bloated and still gives
enough info. It won't check voor callbacks or whatever, just
which parameter b0rked it.

Test if irq's got enabled early, barf about it, and disable them again
The calls made by parse_parms to other initialization code might enable
interrupts again way too early.
This patch detects that, barfs about it and disables them again.
Having interrupts on this early can make systems PANIC when they initialize the
IRQ controllers (which happens much later in the code).
Created attachment 9964 [details]
Detect if parsing parameters enables irq, and notify that.
Some kernel parameters seem to enable irq's somehow.
This script detects that, and notifies the user.
Created attachment 9965 [details]
Prevent a down-read in pci_find_subsys when the pci device list is empty.
The pci_find_subsys gets called very early by obsolete ide setup parameters.
This is a bogus call since pci is not initialized yet, so the list is empty.
But in the mean time, interrupts get enabled by down_read.
This patch checks if the device list is empty before taking the semaphore, and
hence will not enable irq's.
This patch is an adaption of Andrew Mortons patch.
