All KOTDs since 2.6.25-rc7-git2-HEAD_20080331133119
-default are showing the following problem in the logs :
dentry_open called with NULL vfsmount

I was wondering how long I'd be able to get away with that. Question
answered. I'll come up with a fix today.

Or not. I've fixed this problem, but run into others. I'll keep the
list updated.

I've just updated the reiserfs xattr patches to fix the problems.
Tomorrow's KOTD will have the update.

It should contain the following in the changelog:

- patches.suse/reiserfs-kill-xattr-readdir.diff: Eliminated use
of vfsmount-less dentry_open().

Thanks, that made "dentry_open called with NULL vfsmount" disappear.

But unfortnunately, there is another problem introduced with 2.6.25-rc7
that still exists. When I shutdown the system, there is a segmentation
fault during the final umount and the system stops with extra sync but
filesystems still mounted readonly . Nothing in the logs. Syslog seems to
be allready stopped at that time.

Can you switch to console 10 and see what the Oops says?

Sorry, don't have the time to write down the whole message
