After about 2 weeks of uptime I'm getting messages like that:
igb0: Watchdog timeout -- resetting
igb0: Queue(0) tdh = 16, hw tdt = 20
igb0: TX(0) desc avail = 1020,Next TX to Clean = 16
igb0: link state changed to DOWN
igb0: link state changed to UP
Reboot helps, for the next ~2 weeks.
Kernel is GENERIC.
Card is 4 ports Intel

Over to maintainer(s).
I don't suppose this still happens for you? We do not see this in our production load with fbsd8 or fbsd10
For bugs that match the following
- Status Is In progress
- Untouched since 2018-01-01.
- Affects Base System OR Documentation
Reset to open status.
I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
