It was a high CPU load, not a high network load, that caused the kernel
OOPs. The fact that it happened in exactly the same routine, with two
different cards, implies a bug in the 8390 driver.
I'm getting tired of people blaming the card, when this card works under
Windows NT and BSD _without_ crashing the system. Obviously, if there are
problems with the card it can be compensated for in the driver. Apparently,
the 8390 driver for Linux is not very forgiving.
