>Description:
Hi!

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

>How-To-Repeat:
Use FreeBSD 9.0-RELEASE with 4 ports IGB for 2+ weeks
