Thanks. I picked up delta 1.184.2.3 to if_em.c on Thursday morning. The 
system no longer panics on watchdog timeout, but the original problem from 
PR kern/122928 remains - once a watchdog timeout occurs the interface no 
longer seems to receive packets and never properly recovers, short of 
rebooting the system (or perhaps the watchdog timeout is actually a 
symptom of whatever has "got stuck", rather than a cause?).

The PR is still in "feedback" state, but I think I've provided the 
requested information. Is there anything else that I can do to help 
progress this?

Regards,

Neil.
