In late 2.1.x, I tracked down some horrible nastiness with 8390 and SMP, which Alan rectified. Our problem had to do with switching between page 0 and page 1 in the 8390 and, among other things, destroying the multicast table. But there were some other SMP-related issues with the 8390.

I wouldn't be suprised if even in 2.2.x/2.3.x various bad things happen with SMP and 8390-based cards. It's an awful, awful chip when it comes to SMP operation, and it may need some more spinlocks to avoid yet another intermittent failure.
