kernel 2.6.22-11 fails to resume drive correctly

happens every time I suspend/resume with that kernel. I would say this is critical!

not fixed with 2.6.22-11.33

not fixed with -12.

As this is fairly standard hardware (Dell latitude D820), a lot of people will have this problem. I'm still using -10 kernel.

I used git-bisect to come to the following conclusion:

jos@duet ubuntu-gutsy $ git-bisect good
1af621692e22dbd994dcd9162dbeda05bd5080a3 is first bad commit

    Re-add _GTM and _STM support

    Add _GTM and _STM support to libata-acpi and the suspend/resume
    pathway. Minor mismerge in the previous diff - please use this one
    instead.

Hi thanks for report this. Could you please follow the instructions on https://wiki.ubuntu.com/KernelTeamBugPolicies and https://wiki.ubuntu.com/DebuggingKernelSuspend and attach the output? Thanks!

The dmesg after reboot is not helpful here I think. What happens at resume is that the drive does not resume correctly, the filesystem is mounted read-only, and no logs of the event can be written on disk. This makes it hard to give diagnostics, although dmesg at resume time gives plenty of errors.

If I can get it to work, I will try to debug with a serial console, so I can get the relevant output.

I tried with ssh from another machine, but the network is down after resume, and I couldn't get it back online, IO errors. But I typed over some parts of the dmesg, maybe this is helpful.

This patch reverts the broken commit mentioned earlier. It was formatted with git-format-patch against origin (current git), and should apply to latest linux-source-2.6.22.

On my system this patch works, I can suspend resume without problems.

The ACPI code is required to support suspend/resume on basically every HP laptop produced in the past three years, so we can't revert it.

Could you try this patch?

patch seems to work, although there is still the message:
[ 237.932000] ata1.00: _GTF unexpected object type 0x1

sometimes. Not every time. Also the first boot, I could suspend and resume ok, but the next suspend gave a kernel panic. The next reboot, I was able to suspend/resume more than 5 times in a row, no failure since.

Attached is a kern.log that contains all this info (as this time the drive was resumed ok ;-)).

I would say, go ahead and commit, as this is clearly better than what is available now.

Gutsy commit 8db52ac7e3d1bf086356e8e9d62841bce280da11

I just tried a few suspend/resume cycles with latest git, it still works. Thanks!

indeed fixed in current kernel. Thanks.

This isn't fixed for me in 2.6.22-14-generic

Not always, but sometimes, upon resume, I get the errors reported by the duplicates
of this bug:

ata1.01 revalidation failed errno -5
srst failed errno -16
(etc)

eventually the file system remounts ro and is useless only a hard power off.

Ok ignore my last post I'm new to this

unless I'm reading things wrongly, 7.10 release of yesterday still has
the problem but it is fixed *if* you want to download a newer patched
kernel and compile and install it?
