Subject: NETDEV WATCHDOG: eth2 (tg3): transmit queue 0 timed out

	Hi;

	Just noticed this in my logs after 10 days uptime. The interface
is reset and continues to work fine. Looking back through the logs, I
see it happened in 3.3.0-rc4 for the first time. No occurance from
2.6.35.5 util then, and I have run all versions in between. Load on
the interface is light; just connects to a cable modem.

After this, there is a large dump of hex numbers. If this is signifigant
let me know and I will supply any more information or testing.
