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
FreeBSD srv-4-2.lab.local 9.0-RELEASE FreeBSD 9.0-RELEASE #1: Thu Jan 19 18:31:23 UTC 2012     root@srv-4-2.lab.local:/usr/obj/usr/src/sys/GENERIC  amd64

Is there a fix for that problem ?
