With your patch (linux 2.2.10), arla from cvs and inode caching cpp,
I've not been able to provoke the bug. Earlier, without the kernel
patch, things broke rather quickly so this is a big improvement.

OTOH doing "find . -print" (lots of lstat()) in a very large tree
(only one volume) seem to just hang after a while. Any afs access in
other windows make "find" continue. After a while "find" stalls, and
again any afs access in other windows make "find" continue. Seems as
if the communication between xfs and arla is stalling.

I haven't seen this before. It might be the new kernel though.
