I didn't see any significant amount of interrupts when I looked at /proc/interrupts, and there was no traffic running. However, this is also running a hacked up tulip-napi driver, so it could very well be my problem. I have not seen this on any other kernel in several months though... Anyway, if anyone has seen this, I'd like to know. Otherwise, I'll blame my code and start poking at things...
