I think it was unhappy because its interrupts weren't being serviced.
Copying /home/kmacy/suseroot.0 to /home/kmacy/suseroot.1 (NFS -> NFS)
locks the machine up just fine. The machine will also become
unresponsive transiently when running fsck in domU on a filesystem
that is a loopback device mounted over NFS.

Running native mainline 2.6.11.10 NFS transfers don't cause any
problems. To reduce the possibility of it being a benchmark-like SUE
I'll do a clean build from scratch of the dom0 kernel.
