Not in X.

No DDB but I may have configed it away. I should enable the DDB keyboard 
shortcut.

Anyhow again it happened just once so can't analyze too much out of it, 
when I have time I should attempt to simply stress it.

What was clear from this single crash I experienced though is 1) that a 
watchdog timeout was detected and for whatever reason the NIC went 
unresponsive after that, and 2) after detaching and reattaching the NIC, 
the system froze.

So looking forward to debug it further, for instance by giving it crap 
data, and reattaching it lots of times.
