Hi,
During testing I am noticing watchdog timeouts on alc0 when you unplug
the cable from an active interface:
alc0: watchdog timeout (missed link)
alc0: watchdog timeout
This causes the system to lock temproarily for 5 seconds or so every few
seconds. You can plug the cable back in and see:
alc0: could not disable RxQ/TxQ (0x00000008)!
alc0: could not disable Rx/Tx MAC(0x00000008)!
after which the system (and network interface) behaves normally.
I have seen this previously and mailed brad some weeks back, as I know he was
doing work in this area. I am CCing him now.
Cheers
