Hi Jeff,
I've also experienced those messages under 2.4, but they were harmless,
and I never had a machine hang even after weeks of full load (the adapter
was mounted on a stress test machine before being used in firewalls for
months).
So I wonder how you can be sure that it is this driver which finally locks
the bus. Perhaps the system locks for any other reason (eg: race condition).
Have you tried with any other 4-port NIC (tulip or sun for example) ? Sun
QFE would be the most interesting to test as it also supports 64 bits /
66 MHz.
Regards,
Willy
