I saw rather poor performance on the network driver - judging from the
ping behaviour network interrupts only get serviced at the same time as
clock interrupts. I haven't seen network hangs - but then again I never
used it diskless.
This is one issue I haven't really looked into.

I have a diskless unpriveledged FreeBSD domain runnin gon 2.0.7 and FC-3.
Periodically it becomes un-pingable.
I can connect to the console however it is unresponsive.
xm list shows the domain is continuing to consume CPU time.
Is there a way to tell if I have a networking/bridging problem
(which would be quite fatal for an nfs_root system) or the kernel
is wedged in a loop somewhere?
