2.1.90/SMP/3c905 crash.

I tried running linux-2.1.90 on:

Dual Pentium Pro @ 200 MHz
SuperMicro MB P6DNF
3COM 905 ethernet
Buslogic 956 SCSI controller.

It runs for a few minutes then crashes for no obvious reason.
(i.e. no one is even logged in.)
I've heard of problems with this ethernet card and SMP under 2.1.90.
This machine is rock solid under linux 2.1.78. (i.e. it's not a h/w problem)
Attached is the stack trace.

I tried running with the 3c905 as a module. As long as the module
wasn't loaded the kernel seem to run fine. Once I
loaded it and tried the first network op, it crashed.

Like I said this problem as been present since 2.1.87 and I'm getting
concerned it won't be fixed before the 2.2 release. Please don't let
that happen. I would like to help and my office (B.5, Rm W76R) is
about 200 yards from Donald Becker's. Perhaps I could ask him.

Thanks,
Rick Niles.
