I'd be interested to know if /dev/random generates enough entropy
to work as expected in xen unstable. I'd certainly hope that it
would.
I've seen standard Linux 2.4.26 hang with NFS root under high
load. 2.4.27 is about to come out. If we're really lucky someone
might have fixed it.
BTW: I've found enabling swap to a block device seems to
significantly reduce the likelihood of a hang with NFS root.
