I believe the problem was that my program that reads information out of
the drivers (IP, mask, MTU, QLEN, and the MII-diag flags) was in a very
tight loop, and so was almost constantly trying to read the information.

I fixed that problem, and haven't seen the NIC lock up since.  If I
get a chance, I'm going to make a stand-alone GPL version of that code, and when
I do I'll add an option to stress the kernel/drivers and see if I can
reproduce this NIC lockup.

Thanks,
Ben

ifup/down didn't help, but I didn't try reloading the module.
