   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:

End of dmesg :

NETDEV WATCHDOG: eth2: transmit timed out
eth2: transmit timed out, tx_status 00 status 8601.
 diagnostics: net 0ccc media 8880 dma 0000003a fifo 0000
eth2: Interrupt posted but not delivered -- IRQ blocked by another device?

This looks like a problem that several network drivers had recently.
The problem was genirq related and should be fixed in 2.6.23,
so I'm surprised that this happens with 2.6.23.1 but not with 2.6.23-rc4.

I can confirm that my U60 worked fine sixty days with 2.6.23-rc4 without any trouble. With 2.6.23.1, 3com NIC hangs after three or four days...

	Regards,

	JKB
