Hi.
With recent -current I start to get 
May 14 13:32:48 xxx kernel: msk0: watchdog timeout
May 14 13:32:48 xxx kernel: msk0: link state changed to DOWN
May 14 13:32:51 xxx kernel: msk0: link state changed to UP
with ~10 minutes interval usually at the starting of receiving essential 
traffic. I run my on-board Gigabit Ethernet in the 100baseTX mode.
Below is detaled info.
Can anybody help?
