Certainly :) (have been investigating further through the day)
The code was obtained as the patches for 2.4.3, (it was also patched for a
scsi changer, but all the scsi stuff is modules that weren't loaded), and
we used your Red Hat ISO in rescue mode to convert our root partition to
XFS.
I'd been trying to hammer a partition remotely. I'd exported it with
knfsd, but the oops I posted was caused by trying to tar said directory
(locally--no NFS involvement) to a file in its parent (which does contain
some large (~4GB) files.
kernel built with egcs-1.1.2, not very much in it, modules loaded at the
time were nfs, sunrpc, lockd, autofs (but I will test again without any of
those loaded when the box is less busy)--I had removed nfsd and friends.
We tried to recreate this on a second box a couple of hours ago and
failed, so we can't rule out a hardware/other non-XFS problem. Two
immediate potential culprits are the VIA KT133 UDMA and the drive itself
(NB the second box has the same motherboard, but not a WDC drive):

Thanks for the reply. Any more information on request :)
