In /usr/src/linux/fs/pagebuf/page_buf_io.c, for pagebuf_write_full_page,
So it appears to be the forced shutdown, but I don't know what had
caused the forced shutdown. It truly is a mystery to me. I run
VMWorkstation 3.0 on xfs, could this be a problem. Although the VMWare
goons keep telling me that xfs is unsupported, I have never had a
problem up to this time. I don't want to make any conlusions just yet
either. I am keeping a very careful eye to see if it happens again so I
can document it better. This is the very first time I ever encountered
SB Validate errors since using xfs from 2.4.14. My kernel also uses the
preemptive and RMAP12a patches. Could the Rmap12a patch be a source?
This is the last major modification I've made to my 2.4.17 kernel since
Monday (4 days ago). I implemented this patch because I was have
stability problems when I would push my system to it's memory limit by
running multiple VMWare sessions - the VM wouldn't swap properly. The
Rmap12a patch completely fixed my VM problems. My system runs very
steady now at full RAM utilization.
I am not using any neat stuff like xfs_freeze, realtime, etc. etc.
although I would love to play with it later. ;-)

Ok, a couple things... There have been several changes in 2.4.17 - can
you look at the bottom of pagebuf_write_full_page() in page_buf_io.c?
About 8 lines from the bottom of the function, does it say
block_flush_page(page,0), or _unmark_delalloc(page)? If it's the
latter, then it was probably the forced shutdown that caused the
corruption, although I'm not sure what's causing the shutdown.
Are you doing anything fun with this filesystem? Using LVM snapshots,
playing with xfs_freeze, realtime subvolumes? :)
