Hi,
FYI: attached screen-shot is from a server that crashed today when
doing an "umount" of a no longer needed XFS partition on a SSD
(mount options: rw,noatime,nodiratime,nobarrier)
(The operations on that filesystem ended > 1 day before the umount,
and did not show any problem)
Kernel was plain vanilla 2.6.34.
Regards,
Peter Niemayer

Unfortunately the backtrace doesn't really tell what has happened as
the origin of the backtrace scrolled away.

Oh, sorry. Now it's too late for this incident - but if it happens
again, I'll try to do screen-shots also from the "upper" part
of the scroll buffer.
