Totally Out of Ideas on Fixing Network Bug

[Null Ack]

Thanks again Daniel, very much appreciated. Ive been through my CMOS
settings but unfortunately no joy.

So I have been doing more research and I think Im narrowing it down now. In
summary I think:

After a period of no network use, ACPI thinks IRQ 23 isnt needed
ACPI turns off IRQ 23
eth0 times out and wont come back without reboot
ifdown/ifup wont fix it
Im yet to test manually unloading and reloading the module for my Via rhine
II nic to see if that brings it back without reboot. Just waiting for the
timeout.
