           Summary: kernel from different versions hangs with some CD/DVD
                    drives
           Product: IO/Storage
           Version: 2.5
     KernelVersion: all tried (2.4.* and 2.6.*)
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: IDE
        AssignedTo: io_ide@kernel-bugs.osdl.org
        ReportedBy: lars.winterfeld@tu-ilmenau.de


Latest working kernel version: unknown
Earliest failing kernel version: 2.4
Distribution: all tried
Hardware Environment: notebook "Fujitsu Siemens Amilo Xa-2528", output from
`lspci -vvv` attached
Software Environment: n/a
Problem Description:
I want to report a problem with certain CD/DVD drives / controllers, which is
kernel-related as far as I can see. I came to face the problem on my new
notebook (Fujitsu Siemens Amilo Xa-2528). Although I tried the installation CDs
of different distributions (Gentoo, Ubuntu, DSL,...) with different
kernel-versions including some of the 2.4 and 2.6 series all failed to boot.
Here is part of the log:

Mar  7 20:51:59 (none) Freeing unused kernel memory: 376k freed
Mar  7 20:51:59 (none) ide-cd: cmd 0x5a timed out
Mar  7 20:51:59 (none) hda: irq timeout: status=0x58 { DriveReady SeekComplete
DataRequest }
Mar  7 20:51:59 (none) ide: failed opcode was: unknown
Mar  7 20:51:59 (none) hda: ATAPI CD-ROM drive, 0kB Cache
Mar  7 20:51:59 (none) Uniform CD-ROM driver Revision: 3.20
Mar  7 20:51:59 (none) hda: status error: status=0x58 { DriveReady SeekComplete
DataRequest }
Mar  7 20:51:59 (none) ide: failed opcode was: unknown
Mar  7 20:51:59 (none) hda: drive not ready for command
Mar  7 20:51:59 (none) hda: status error: status=0x58 { DriveReady SeekComplete
DataRequest }
Mar  7 20:51:59 (none) ide: failed opcode was: unknown
Mar  7 20:51:59 (none) hda: drive not ready for command

Last error messages are repetitiously outputted until the computer freezes /
hangs. By googleing the error-message I found that it is not a problem of my
computer alone. ( http://ubuntuforums.org/showthread.php?t=699244 ,
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/182996 ,
http://forums.gentoo.org/viewtopic-t-666680.html?sid=36e4b5379601abe70a5f2fc5420e1765
, ...)

As far as I can tell, the problem appears as soon as the CD/DVD drive is
accessed, which is of cause done by almost any linux installation or "live" CD.
So I tried a Gentoo-based boot-cd called "unattended gui" which does not mount
the cd filesystem (btw: kernel config
http://unattended-gui.sourceforge.net/wiki/index.php?title=Bootcd:kernel )

Once booted, I ran lspci telling me:
00:0d.0 IDE interface: nVidia Corporation MCP51 IDE (rev f1)
00:0e.0 IDE interface: nVidia Corporation MCP51 Serial ATA Controller (rev f1)

The drive inside my notebook is recognized as "hda: Optiarc DVD RW AD-7540A,
ATAPI CD/DVD-ROM drive", but google tells me the problem (or similar) also
appears on "PHILIPS DVDR1660P1", "BENQ DVD DD DW1620", "LILITE-ON DVD
SOHD-16P6P9S", "RICOH CD-R/RW MP7040A" and other.

The pre-installed Windows Vista can read and write DVDs.

Some log (from the "unattended"...):

http://www.winterfeld.de/Lars/amalio/scsi
http://www.winterfeld.de/Lars/amalio/uname-a


Since I also program in C, I took a look at some ide*.c files where I found the
error message, but I have no clue about how the kernel works. So, I would be
really grateful for any suggestions and if more information is needed, then
please just ask.

Could you try some newer kernel (2.6.25 or 2.6.26-rc6), there has been a lot of
fixes for ATA/ATAPI support since 2.6.24.

------- Comment #3 from lars.winterfeld@tu-ilmenau.de  2008-07-08 03:01 -------
For 2.6.24 I found some config, which caused the error not to appear (see
bottom of http://gentoo-wiki.com/HARDWARE_Fujitsu-Siemens_Amilo_Xa2528 ). I
could even read from the drive. Now I'm using 2.6.25-gentoo-r6 and the error
appears again (dmesg attached above) and the device is no longer present in
/dev but the notebook boots (with a delay of 6 minutes or so).
I'm still looking at the diff of the kernel-configs. Couldn't yet find
anything, which could have caused the problem. (So it could be the fault of
"lot of fixes" ;-) If someone could tell me some options which could be related
to the problem, I would try the combinations of them and post the log-files.

This actually seems to be a controller specific issue (quite surprising at
that).
Could you try the fix proposed for bug #11659 (as after the fact it seems to be
same issue):

wanted to try it with 2.6.25.9, but include/linux/ide.h already contains a (1
<< 26) flag: IDE_HFLAG_ABUSE_SET_DMA_MODE. all others up to 1<<31 are also
used... because i do not want to break something else, i would try to store the
"use-workaround"-flag somewhere else. what would you advice?

------- Comment #7 from bzolnier@gmail.com  2008-11-10 15:40 -------
Hmm, the safest bet would be to define IDE_HFLAG_BROKEN_ALTSTATUS flag to some
flag that is set unconditionally in amd74xx host driver -- i.e. adding:

        IDE_HFLAG_BROKEN_ALTSTATUS = IDE_HFLAG_PIO_NO_BLACKLIST,

at the end of enum { } clause.

you are my hero! ;-)
it worked. i tried it with the original source of linux-2.6.25.9
without the patch the described problem appears, with the patch (and nothing
else changed) the kernel boots just fine, /dev/cdrom gets created and i can
read files from it.
i'm now going to attach some files (dmesg, maybe from other kernel versions,
etc.) just for references...
i think, afterwords you can mark this bug as closed or resolved...
would like to see this in the next kernel version... :-)

by looking through the dmesg output, you can see that the patch
http://bugzilla.kernel.org/attachment.cgi?id=18748&action=view did it for me in
all tested versions from 2.6.25 to 2.6.27.
i patched the original kernel ("vanilla-sources" as its called in gentoo) and
different sources which are patched by gentoo-developers. (main drivers part
should be the same...)
i patched drivers/ide/ide-iops.c, drivers/ide/ide-probe.c,
drivers/ide/pci/amd74xx.c as described and include/linux/ide.h like this:
        IDE_HFLAG_NO_UNMASK_IRQS        = (1 << 31),
+       /* AltStatus register can be unreliable*/
+       IDE_HFLAG_BROKEN_ALTSTATUS = IDE_HFLAG_PIO_NO_BLACKLIST,
  };


what is that "Clocksource tsc unstable" about?

Sergei: I looked into it (under QEMU for now) and adding msleep(1000) +
printk() to ide_init() causes the "Clocksource tsc unstable" to appear before
IDE initialization so it seems that the issue is caused by some other kernel
code and IDE is just unlucky to be initialized at same time as clocksource
watchdog triggers.

I guess it's caused by mspleep(1000) call itself. If ide_wait_not_ready() is
touching the other watchdogs anyway, I don't see why it shouldn't touch the
clocksource watchdog too.

Looks like it hasn't been a wild guess. The clocksource watchdog timer handler
gets run every half second. :-)
