keyboard + if_nfe oddity

Okay, here's an odd one.

I have an Asus M2NPV-VM board using the nfe driver from 
http://www.f.csce.kyushu-u.ac.jp/~shigeaki/software/freebsd-nfe.html

Traffic is moderate (approx 7Mbps) and every couple of days, the
nfe device just stops talking to the outside world. I do see one
type of error in the logs:

Jul 12 10:08:33 cwpro1 kernel: nfe0: watchdog timeout (missed Tx interrupts) -- recovering
Jul 12 10:09:04 cwpro1 kernel: nfe0: watchdog timeout (missed Tx interrupts) -- recovering


The solution?

Plug in a keyboard (PS2). As soon as ukbd is probed, up fires the
ethernet device and we're talking again.

So, any ideas? This box is in production so debugging time/possbilities
are limited.
