I have a 486DX4-100 system that is doing make worlds fine, but
generates a lot of:
de0: system error: master abort
messages with a current kernel. With a 2.1R kernel it was
generating illegal interrupt errors for de0.
Any guess if this is bug in the if_de.c driver or a hardware problem?
The rate of messages is 5-30/hour on a system not doing much
networking.
