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

I had a similar event last night, on a P4 on an Asus P4P800.  The current
driver is much less prone to this lockup problem than it used to be.  In my
case it does not have to be in a high-load situation, it appears to happen
rather randomly (and *very* infrequently)

The updated driver has been in HEAD for some days and the problem
should be fixed there thanks to Pyun. See last commits to src/sys/dev/sk/*
