2.6.27-6? You mean 2.6.27-rc6?

Anyway, you need to try this patch:

http://oss.sgi.com/archives/xfs/2008-10/msg00105.html

which I posted a few days ago that fixes the latest reproducable
case of this shutdown that I know of.

If that patch doesn't fix it, what you need to do is get the
filesystem into a state where this sequence of commands can be
repeated:

# mount <dev> <mntpt>
# cd <mntpt>/some/dir/in/fs/where/error/is/occurring
# touch <somefile>
[ filesystem shuts down ]

At that point, if you provide me with an xfs_metadump image and
the exact commands to reproduce the shutdown, I will be able to
find the problem and patch it pretty quickly.

Cheers,

Dave.
