Bug#428431: linux-image-2.6.21-1-amd64: kernel oopses with XFS + device mapper (dm-crypt)
Package: linux-image-2.6.21-1-amd64
Version: 2.6.21-4
Severity: grave
Justification: causes non-serious data loss
I did nothing fancy like suspend or resume or anything, this was just
a clean boot, working hacking, using mpd and listening to music, and
that happened. Unable to remount my partitions properly, I lost my
current opened work.
dm-2 is a dm-crypt (using luks) mapping, holding an XFS partition.
I've heard other people had problems with XFS on 2.6.21 as well. I never
had any problems with .20 so far (and I've used it for weeks without a
single reboot, and with fancy things like str and so on).
Here is the trace from my kernel.log:
