Crash on 2.6.21.7 Vanilla + DRBD 0.7

[Laurent Caron]

Hi,

I did compile a fresh 2.6.21.7 kernel from kernel.org (no distro patch, ....), and latest svn (3062) 0.7.X drbd.

After just 2 days of uptime, I did experience another crash.

I wonder if it is an XFS related bug, a DRBD one, or related to XFS on top of DRBD.

This bug seems to occur with intensive IO operations.

What do you think about it ?

Thanks

Laurent
