It works fine with the Intel Dual Port Pro-1000 MT adapters without
these problems. I am using testing scenarios
with Jumbo Frames as well. I am guessing the PCI bus contention is high
due to the disk I/O bandwidth and
this is causing conditions the adapter does not normally see.
Documentation states that this message should be very
rare, and not spool off into the logs at this rate.

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

the adaptec starfire driver goes into

generating a deluge of messages such as:
ethX: PCI bus congestion, resetting Tx FIFO window to X bytes

several days, the PCI bus totally locks up

high bus loading rates, the starfire card will completely lock the bus
after 3-4 days
of constant Tx FIFO reconfiguration at very high data rates with
protocol splitting and routing.
