I tried 2.6.22-rc4 (with Tejun's patches) to see if it had improved - no.
Note this is a different (desktop) machine to that involved my recent bugs.
The machine will work for days (continually powered up) without a
problem and then exhibits a filesystem failure within minutes of a resume.
I know xfs/raid are OK with hibernate. Is lvm?
I have LVM working with hibernate w/o any problems (w/ ext3). If there
were a problem it wouldn't be with LVM but with device-mapper, and I
doubt there's a problem with either. The stack trace shows that you're
within XFS code (but it's likely its hibernate).
You can easily check whether its LVM/device-mapper:
1) check "dmsetup table" - it should be the same before hibernating and
2) read directly from the LV - ie, "dd if=/dev/mapper/video_vg-video_lv
of=/dev/null bs=10M count=200".
If dmsetup shows the same info and you can read directly from the LV I
doubt it would be a LVM/device-mapper problem.
