Hi Ian,
Thanks for your response.
The "before" and "after" are with respect to the problem i.e. network stops
responding. Xend should be running at both times.
I've followed your instructions on looking at /proc/interrupts and it appears
you are correct.
The interrupts on the eth0 stop incrementing suggesting that the driver has
indeed locked up.
/proc/interrupts for a normal kernel are as follows
CPU0
0: 89746 IO-APIC-edge timer
1: 1108 IO-APIC-edge i8042
8: 0 IO-APIC-edge rtc

Doing a diff between the boot.msg of a normal kernel and a xen kernel gives me
the following. Its a little verbose .. sorry.
So do you think its an issue with the network card driver or is something else
happening?
