I'm having trouble with wm0 on two different Thinkpads, both running
very recent kernels.  For one thing, they're slower than they used to
be.  I could manage 550M-580M bps using from them to a Dell with bge0;
now, I rarely hit 350M bps and I'm under 200M bps going from one to the
other.  Second, both machines sometimes seem to forget how to talk on
them, until I ifconfig the interface down and up.  On one, I could
reliably trigger it by displaying Youtube videos, which I really don't
understand...  My suspicion is that it's losing interrupts, or possibly
that there's a timer issue.

Is anyone else seeing that?
