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?
