Yes, I didn't mean to imply that XFS wasn't affected - I was just
trying to reduce the set of possible sources of the problem.

That makes some sense, at least (i.e. that switching off quota
doesn't fix the problem).

I would suggest trying the CVS code if you can - that is now at
2.4.13-something and there's plenty of changes in there.  Maybe
this problem has been diagnosed & fixed in the base kernel - the
fact that earlier versions work OK suggests (but doesn't prove)
that the problem is coming from outside XFS.

I'd suggest booting the 2.4.7-xfs kernel on both machines for now,
until this issue is resolved.

cheers.
