I just wanted to let the developers know that I'm having similar problems concerning interrupts with networking dying as well. Running a stress test of kvm using an EnGarde Secure Linux 1.5 guest OS. Under a heavy network email load, the guest OS networking gets knocked out - unable to ping, ssh, etc. Can only get things started again by going into vncviewer and restarting the networking services from there.
