    Hello,
Since I have installed a 2.6.23.1 linux kernel on my U60, I can see several NETDEV WATCHDOG. This trouble never occurs with 2.6.23-rc4. 
This bug occurs after a random uptime.
I have made the same constation this evening on a amd64/up with two 3C905 and a 2.6.21.3 linux kernel... This evening, I have rebooted my U60 with a 2.6.23.8 kernel and the same 3C905 runs fine. Wait and see (but I suspect a kernel bug...). 

	For main linux kernel list:
