My point was that it should be possible, not that one OS dealt with this
issue better than another.

My guess is that the interrupts are not getting acknowledged properly in
the interrupt handler for the NICs (perhaps the driver gets confused if
the interrupt is not coming from the NIC and it does something bogus).
You should be able to set a breakpoint in the interrupt handlers (do this
just before the system does it's spl0 to enable normal interrupts) and 
verify what is happening.
