[eepro100] Second eepro100 recognized "Receiver Lock-Up bug", but nothing gets done about it....

[Graham Wooden]

I did notice the IRQ sharing in /proc/interrupts of eth0/eth1 on Int 9, and
now, after I rebooted with that noapic statement, dmesg is also showing
Interrupt 9, when before they were on separate IRQs.

Am I wrong to think that the OS can handle the NICs on the same IRQ? It can
right? it just when it comes to Address location is where it will freak.

Anyways, I am not sure what to think right now on this. 
Any help or suggestions would be great and appreciated!

The receive lock-up work-around is pretty rare, and likely unrelated to
your problem.

This sounds like an IRQ mapping problem.
Try passing the kernel option 'noapic' on the boot line.
