Is this problem still present in 2.6.15?

Yes, the problem is still present in 2.6.15, almost unchanged.

Notes and differences from previous tests:

- I just downloaded and compiled the latest stable 2.6.15 source from 
kernel.org and installed it in my Debian (testing, normally using 2.6.12). 
However X.org did not start, so I did the testing in single user mode and I 
had no syslog; the usual errors showed up on the console, though.

- When started from 2.6.15 as root, cdrecord says:
  "Error: cannot gain SYS_RAWIO capability. Is cdrecord installed suid root?"

[ adding Jens to cc: ]

Could you post again "the usual errors" just to make sure we are focusing on the
right thing?  What cdrecord version are you using?

The usual errors are:
  ide-cd: cmd 0x3 timed out
  hdc: lost interrupt
and then the IDE bus becomes unusable until reboot (in this case, being in 
single user mode, I can't do anything at all).

cdrecord version = Cdrecord-Clone 2.01.01a3
sg driver version = 3.5.27

The lockup seems to be related to some specific type (size?) of data exchange, 
possibly concerning the dvd_read_structure command, because leaving the drive 
empty or using a (cdrecord-unsupported) DVD-RW disc gives only an 
informational message, while CD-RW and CD-R cause the problem.
(however, cdrecord compiled from the same sources has no problems under cygwin 
on the same hardware)

Thanks.  Would it be possible to obtain dmesg and also strace output for cdrecord?

dmesg and strace with 2.6.15 are shown below. dmesg looks a bit mangled (maybe 
because of booting my 2.6.12 system with 2.6.15? 
(is it OK to put all this stuff in the message body or should I use 
attachments?)

I believe that the original tracing I did with 2.6.12 may still be 
significant. My original notes of the cdrecord call stack are (in calling 
order):
- read_dvd_structure() (cdr_drv.c:325)
- scg_cmd(scgp) (scsi_cdr.c:1106)
- SCGO_SEND(scgp) (scsitransp.c:399) 
- ioctl(scgp->fd, SG_IO, &sg_io) (scsi-linux-sg.c:1239)
- (doesn't return until timeout)
(I'm not sure if those line numbers refer to 2.01.01a3 or to 2.01.01a1)

I can insert printf() into cdrecord and printk into the kernel() if you wish 
(though this would be a lot faster with 2.6.12 than with 2.6.15, unless I 
solve the X.org problem).

Thanks, does it work fine if you disable DMA with hdparm?

Would it be possible to try reproducing this bug on machine without ALi chipset?
It would allow us to limit the problem to alim15x3 driver and ping ALi folks
about the problem.

Also can you confirm that if you just throw a pre burned CD into the drive and
mount it with DMA enabled it reads the disk and the file system works fine ?
That wil help understand if it is some kind of buffer alignment issue

Well, I've tried all the media I could find: DVD, Audio, self-burned cdrom and
pre-burned cdrom (bought). All of them reads fine, even with DMA enabled, and
I've used audio, video, rpms and clip-arts.

To Bartlomiej:

If I disable DMA with hdparm, it works fine even in 2.6.15: I tried "cdrecord 
-checkdrive" and "cdrecord blank=fast", both successfully. 
In fact, it seems to work better in 2.6.15 than in 2.6.12 because with DMA 
disabled the speed is now high enough to reach the drive's minimum 
requirement (10x) so it can now write to disk.

I don't think there is a positive way to prove that the lockup happens only on 
machines using ALi M5229 rev c7; however, before posting I searched the Web 
for people having the same problem: the two instances I found referred to the 
same ALi M5229 controller and the same c7 revision. Of course, people having 
the HD on the same IDE bus as the CD writer will experience a full system 
lockup, so they could have more difficulties in diagnosing it (or to install 
at all).
Perhaps it could be a good idea to notify ALi folks as you propose (did they 
write the low-level driver, I gather?). Maybe they changed/added the meaning 
of a 'minor' bit in a DMA register when upgrading the chip to rev c7.

To Alan:

I successfully copied from CD burner to HD with 2.6.15 and DMA enabled:
- the entire content of a printed CD-ROM
- the entire content of a CD-RW
- the entire content of a printed DVD-ROM

However, Jeff Wiegley (who filed bug #4514 for a similar problem on similar 
hardware) said he had reading problems too. This difference is the main 
reason why I filed this problem as a different bug.

Hm, this looks similar to http://bugzilla.kernel.org/show_bug.cgi?id=4514

Could somebody try 2.6.8 kernel?

I didn't find a 2.6.8 (is there a live distribution using it?) but I tried:

- 2.6.7 (Knoppix 3.6): works fine (even with DMA active).
- 2.6.10-5 (Ubuntu live 5.04): locks up (only if DMA active).

However, 2.6.7 does not accept the ATA: interface but it uses ATAPI: with a 
different bus address (was ATA: introduced in 2.6.8?).
Also, cdrecord on 2.6.7 can't actually write data to the CD because of "DMA 
speed too slow", so I couldn't do a complete test; anyway, no lockup happened 
at the usual point (for both "-checkdrive" and "blank=fast").

Perhaps I've got a different problem, because I cannot get it to work with _any_
2.6 kernel. I've tried 2.6.0, 2.6.5, 2.6.8.1, 2.6.9, 2.6.10, 2.6.11, 2.6.14,
2.6.15. All of them hang the ide driver when trying to use dma + burner, and
works without dma. I'm using an Turion64 processor, though, if that makes any
difference (in 64-bit). Same errors as before:

ide-cd: cmd 0x3 timed out
hdc: lost interrupt

I've used:

cdrecord -v -dummy -driveropts=burnfree dev=/dev/hdc <FILE>

Thanks for testing.

> However, 2.6.7 does not accept the ATA: interface but it uses ATAPI: with a 
> different bus address (was ATA: introduced in 2.6.8?).


No, this is probably cdrecord's issue.

Below is a sort of "poor man's tracing" of some kernel function calls on my 
machine leading to an IDE lockup.

It is definitely not complete or exhaustive: I just added a number of printk() 
at entry and exit points of some functions and printed out a few values (I 
know next to nothing of inner kernel workings).

Legenda:
-->            function call (also ==>, no significant difference)
<-- (r)        function return (also <==) with return value r
<-- (r) -retN  n-th return point from the middle of a function <sigh>.
    <n>        n-th arbitrary checkpoint iside a function 

Note IRQ entry and return. Feel free to ask for details/changes/values.

I forgot: the 'tracing' has been done on 2.6.12 (I did most of it last month).

Is the device driver interface consistent across minor kernel numbers?
I mean, if I copy alim15x3.[ch] from 2.6.8 source to 2.6.12 source, can I 
still compile 2.6.12 or does it all break down horribly?
In the former case, it could be helpful in deciding if the problem's source 
lies in the driver or elsewhere.

(I apologize if this is a stupid question; I just lifted the kernel hood a 
couple of months ago)

probably would break down, kernel internal APIs change rapidly


Alan, does this look like alignment issue?

data_len=0020 so we should be safe unless this chipset
has really weird alignment requirements (?)

Looks like alignment to me, I'm not aware of any odd rules for ALi but this is
an ALi/ATI combination and that may have funnies of its own ?

I tried messing up with xferlen at the entry of cdrom_start_packet_command(), 
first changing it (only when it was 0x20) then just setting it to a fixed 
value (0x04), so that it set up the chipset for a shorter packet transfer.

I expected to get errors, or at least odd behavior, but what I see is:
- the commands preceding the lockup behave differently 
  (returning error, I suppose: generic_ide_ioctl returns -22)
- the command where it locks up behaves exactly as it did before: 
  same calls, same results (at least on visual check), then lockup  
  (I expected it to return error like the others).
- 'strace' of cdrecord seems to give the same results as before.

I know such a test may make little sense, but in case it may be useful...
(feel free to ask for more meaningful tests)

A wild guess: could it have something to do with getting the 
answer/acknowledge/whatever back from the drive after sending the command?

What is actually happening is this:
* READ_DVD_STRUCTURE command (0xa) is send to the device
* it fails for some reason and driver queue REQUEST_SENSE command (0x03)
* REQUEST_SENSE timeouts and device/driver is unable to recover

It may be useful to see while READ_DVD_STRUCTURE fails be adding some debugging
info printing value of 'stat' / 'err' variable for REQ_BLOCK_PC requests in
cdrom_decode_status() [ just before cdrom_queue_request_sense() ].  Sorry but I
don't have patch handy ATM.

Inside IRQ handler ide_intr(), in cdrom_decode_status(), inside REQ_BLOCK_PC, 
before the call to cdrom_queue_request_sense():

  stat=81, err=84, sense_key=5
  (with a CD-RW in the drive)

If I try with no disc in the drive, I get a number of (stat=81, err=36, 
sense_key=2) and also a single one (not the last one) same as the one above 
(err=84, sense_key=5).


Other notes:

- I've also noticed, going back through the 'tracing', that there are many 
calls to generic_ide_ioctl returning (-22), both with CD-RW and with no disc. 
I assume that's normal, but just in case...

- I'm still using 2.6.12 because of the convenience of my old tracing points; 
tell me if I have to use 2.6.15.

- don't worry about writing test patches: you're already doing the work that 
counts! I have no trouble following your directions.

I repeated the test with 2.6.15 and also tried a DVD-RW disc (which does not 
lock up the IDE bus):

(cdrecord dev=ATA:1,0,0 -checkdrive)

No disk in the drive:
  stat=81, err=36, sense_key=2  [this one repeated 25 times]
  stat=81, err=84, sense_key=5
  stat=81, err=36, sense_key=2
  stat=81, err=84, sense_key=5
  stat=81, err=36, sense_key=2  [this one repeated 28 times]
  
DVD-RW in the drive:
  stat=81, err=84, sense_key=5  [this one repeated 2 times]
  (no lockup)

CD-RW in the drive:
  stat=81, err=84, sense_key=5
  (lockup: cmd 0x3 timed out, etc.)
  
Could it have something to do with the handling of the drive's reply?

Hello
On November 2005, I opened a detailed bugzilla on redhat.com:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=172278 and wrote to the
kernel mailing list about this bug without getting an answer. FYI, the archive link:
http://www.uwsg.indiana.edu/hypermail/linux/kernel/0511.2/0082.html
My bug reports and Enrico's one definitely describe the same issue. So I'm
adding myself to this bug, hoping I can help.

are there any changes to this bug?
i also got the barebone st20g5 with the ali 15x3 chipset.
cant burn correctly since half a year, that bug is making me crazy
anybody got a patch for it?

Hello,

I was able to reproduce the very same problem with kernel 2.6.11.12 and 2.6.16.
I have the same ide controller:

$ lspci|grep IDE
0000:00:16.0 IDE interface: ALi Corporation M5229 IDE (rev c7)

The problem appeared after I changed my motherboard (my previous motherboard had 
a VIA ide controller) so I think we can exclude anything not related to the 
ali15x3 driver.

The error messages and behaviour are identical to the ones already described by 
other users.

HTH, HAND

There seems to be a consensus about the problem likely being in the ali15x3 
driver with the ALi Corporation M5229 IDE (rev c7) IDE controller. 

For Bartlomiej:
did you notify the driver's author(s), or should I do this (as originator of 
this thread)?

plz notify the driver's author, perhaps there is a solution coming....
if not ill use ebay for kicking this chipsets out n buy non ati products...

Enrico: nope, please do so.

[self-correction: the driver is alim15x3, not ali15x3]

What is the corrent way to contact the maintainer(s)?
Should I email the addresses listed in alim15x3.c (Clear Zhang could probably 
be the right person), or is there an 'official' way to do this?

I didn't see any mention of storage low-level drivers for specific chipsets in 
the kernel bug tracker page.

Clear Zhang appears to have left ULi

I have a few dozen of the Shuttle ST20G5 systems with the ALi M5229 IDE
controller that exhibits this problem.  I would be happy to loan one of these
systems to the appropriate developer if it would help resolve this problem more
quickly.

Good news everyone :)

2.6.16.10 fixes the problem for me. Look at this:

--- a/drivers/ide/pci/alim15x3.c
+++ b/drivers/ide/pci/alim15x3.c
@@ -731,6 +731,8 @@ static unsigned int __devinit ata66_ali1

                tmpbyte = (tmpbyte & (~0x02)) | 0x01;
+       else if (m5229_revision == 0xc7)
+               tmpbyte |= 0x03;
        else
                tmpbyte |= 0x01;

Thank you!

Great! I look forward to getting my machine back (from the repair shop) and 
trying it out!

I've just tried with kernel 2.6.16.11 compiled with Fedora Core 5 rules.
I've been able to do a cdrecord -atip, to blank and burn a CDRW.
For DVD burning, this seems to be OK, I've just had a scsi command error at the
beginning, but everything worked well.
Who should we thank for this fix?

I built and installed a 64-bit version of 2.6.16.11 on a Shuttle ST20G5.  The 
IDE CD/DVD now works properly.

Got my PC back (at last!).

I tried with a freshly compiled 2.6.16.14 on a Debian testing (Etch): I also 
got a SCSI error, presumably the same as Hubert's (see below) but the erasing 
and burning commands worked fine at full speed (I used a CD_RW); I also did a 
successful file compare afterwards, re-reading it from the other CD drive.

Here is the error that appeared between cdrecord's messages "Supported modes: 
..." and "Starting to write ..." when writing (not when erasing):

  Error: Cannot gain SYS_RAWIO capability. Is cdrecord installed SUID root?
    Operation not permitted.

The same error message was shown when operating both as user and as root.
Should I close this bug or does that error message require further 
investigation?

Ah, and *many* thanks to whoever fixed it! :-)

I got something similar without an ALi ide chipsetdriver.

I got an nvidia CK804.

Here is some /var/log/messages output:

Nevertheless, the burned dvd with DMA turned off (by hdparm) is ok regarding the
windows shareware cdcheck. Also after a reboot I gained access to that dvd under
linux. I couldn't get access to the dvd before reboot. 

I hope, this report is related to this bug.

Reading seems to be ok, when mounting manually, and not with
gnome-volume-manager/hal. So it might not be related to the kernel/ide...

|-------^^^^  should be GSA-4163B

After disconnecting the defect burner everything worked like a charm.
There is no kernel bug, that leads into these problems.

I'm sorry for the noise.

Hello 

I had the same issue with an Asus A8R32-MVP - ALi Corporation M5229 IDE (rev
c8). As there are no problems, only solutions:

This one is better :/

Maybe should bug status be changed to closed ...

The patch from this bug has been included since kernel 2.6.18.
