Subject: delalloc filesystem corruption

Ted,

Thanks for your quick reply.  With the newest rc8-based snapshots I am no
longer getting segfaults, unless you wanted me to roll back to the
rc6-based snapshots to reproduce the segfaults.

Per your latest request I disabled delalloc, and voila, no more data
corruption! Then I enabled delalloc and disabled mballoc and file
corruption to /lib/rc/init.d/nettree returned. So delalloc is the culprit.

I hope this will help figure this out.

Thanks again,
Gary
