Hmmmm, that indicates a problem, usually a hardware problem.

This is bad.  It's reporting that the machine is too slow to process the
packets.  Do you have some sort of APM feature turned on?

This is because the card has most features disabled at this point.

You can work around the symptoms by setting the following module parameter:
/* Maximum events (Rx packets, etc.) to handle at each interrupt. */
static int max_interrupt_work = 20;

options 3c59x max_interrupt_work=200
