Subject: nfsd oops
Date: Tue, 05 Aug 2003 11:42:05 +0100 [thread overview]
Message-ID: <3F2F89FD.BAE37A08@moving-picture.com> (raw)
I had the following oops on a machine that is an NFS server to diskless
clients.
The machine is running a rather old kernel - 2.4.18 with XFS v1.1 -
upgrading the kernel will not be a problem, although I would appreciate
if anyone knows if this a known problem (and fixed in a later kernel)
...
Thanks
James Pearson
