My motherboard has a built-in ethernet port that is handled by the sk 
driver. I'm running FreeBSD 6.1-RC on amd64. When the network card is 
under high load, it often kills any current connections and leaves the 
message "sk0: watchdog timeout" in dmesg. I've seen previous posts on this 
issue, but the problem doesn't seem to be resolved. This issue makes these 
network cards unusable in production environments.

Relevent dmesg output:
skc0: <Marvell Gigabit Ethernet> port 0xa000-0xa0ff mem 
0xfbb00000-0xfbb03fff ir
q 17 at device 10.0 on pci0
skc0: Marvell Yukon Lite Gigabit Ethernet rev. (0x9)
sk0: <Marvell Semiconductor, Inc. Yukon> on skc0


Any help would be appreciated,
Miles
