OK - thanks to Eric's help things appear back to normal now(is there is
such a thing). The install CD I have is the first one that was put out
- I didn't find xfs_repair/xfs_check on it. Luckily I have some space
on my /boot partition (mounted to a temp location) where I copied them
to(acually all the xfs_* progs some others are required). xfs_check
found a few "link count mismatch.....disconnected inode" errors(I have
one written down incase there is interest - lots of typing) - I actually
have/had another directory that was causing me the same problem from a
few weeks back.
xfs_repair -n basically found the same things "entry .... references
non-existant inode.... would have cleared inode...."(I wrote one of
these monsters down also in case there is interest)
It didn't appear it wanted to destroy the fs and these were junk
directories/files anyway, so I ran xfs_repair on the parition which
dumped a few small files into lost+found, and allowed me to remove the
previously offending directories&files after the system booted normally.
The big question now is, what caused this in the first place ??????
My hats off to yourself(Eric) and all the other XFS
developers/contributors. I've been using linux+XFS on all my linux
installs since before the first installer came out(over 1 year ago
now??) - and have not expereinced an issue before this.
Much Thanks,

Subject: Kernel Oops'
I'm having a kernel Oops occur when trying to rm or ls the directory:
/tmp/orbit-hengeje1
I can mv it to a different name.
After the mv it's automatically recreated, I can then and rm,ls,etc..
the recreated dir just fine.
However, I can not remove the renamed directory though - gets an oops
every time.
The first rm -fr /tmp/orbit-hengeje1 will complete but message: "Can't
remove directory ... - (not empty)"
The second try of the command will hang and generate the Oops in the
syslog.
I guess its trying to tell me - If at first you don't succeed, don't try
again ;-)
Kernel versions and Oops'(direct from syslog):
