Hi,
I see that this error has alredy been observed with 2.6.17-mm; I'm
running kernel 2.6.18-rc5 (x86, UP, with PREEMPT) and may have
additional information. In my case the FS was affected by 2.6.17
directory corruption (I forgot to run xfs_repair on this machine); after
the FS was shut down I rebooted the machine (with init=/bin/bash, rootfs
on ext2, so it was not affected) and mounted XFS partition read-only to
recover the log.
I tried to reproduce with "simple" crashes (i.e. write a file and
reboot, I don't want to trash the FS too much ;)) without success, so
the error may be related to directory corruption.
