Subject2.2.18 eepro100 hangs (cmd_wait for(0xffffff80) timedout with(0xffffff80)!)
Date
Hi,

600mhz celery 2.2.18 vanilla, intel 815EE mobo, onboard eepro100 and pci
3com 905b. Happens when traffic is high to the eepro.

FWIW, the 3c905 (3c59x module) also reports 'too much work in interrupt' but
it did not hang like the eepro100, and by adding max_interrupt_work=40 with
modprobe, that also solved the warnings. But the intel card actually hangs
after it shows those warnings, so we thought it was a problem.
