SubjectXFS lockups in 2.6.17.13
From
Date
Morning,

Please do Cc me as I'm not subscribed. Thank you.

I've been experiencing issues with the XFS filesystem. I use SATA
Seagate ST3120026AS disk on which I have two partitions. First one is
used as XFS root partition and the second one is a LVM physical volume.

On my logical volumes I run XFS. I've started getting the lockups /
oopses after having been running the system for a couple of days. It
either results in the complete lock-up or IO operations become very
unstable and dmesg showing errors shown below.

Details:
distro: debian/sid
kernel: 2.6.17.13
xfsprogs: 2.8.11-1
lvm2: 2.02.06-2

I've tried rebooting into single mode to minimize the number of daemons
running and then trying to create files on the partition affected (/usr)
reading them, listing contents, etc. Nothing happened. But it started to
show errors once I issued apt-get install something.

After that when I tried to ls /usr I got the IO Error message. Please
find the kernel output below.

I've gotten this error several times:

Filesystem "dm-0": Corruption of in-memory data detected. Shutting down filesystem: dm-0
Please umount the filesystem, and rectify the problem(s)

This problem affects 2 of my systems which don't run the same hardware
but have roughtly the same software and config. Can you please advice
if this is related to a bug in kernel or userland and suggest some fix
for that if possible?

BTW: please let me know if I've forgotten to mention some details that
you could find helpful. Thanks for your help.
