What is not functioning? - Do you see an interface when you type "ifconfig"? - Are the Rx and Tx counters not incrementing? - Can you check "cat /proc/interrupts"? - Is the ethernet cable link light on? Linux ile 2.6.23-rc5-amd64 #1 SMP Mon Sep 17 01:12:09 UTC 2007 x86_64

It looks like you received and transmitted quite a few packets. If you perform a ping, do either of the counters increment? Also, does the interrupt count increment for eth1 (i.e. 15)? Once in the failing state, can you send me the output of "ethtool -d eth1"? as I said first: "the forcedeth driver is broken on Nvidia MCP51 since (at least 2.6.21.6); works perfectly with 2.6.18" this bug report is about 2.6.23-rc5-amd64 $ sudo ethtool -d eth1 Cannot get driver information: No such device Comment #2 gave you a working example on 2.6.18-5-amd64 if you want to compare Ok, I didn't realize that Comment 2 was on working system. In the dmesg trace I see the following: eth0: forcedeth.c: subsystem: 01043:81bc bound to 0000:00:14.0 net eth2: device_rename: sysfs_create_symlink failed (-17) udev: renamed network interface eth0 to eth2 Not sure what the renaming is all about. What happens if you manually perform "ifconfig eth0 up" or "ifconfig eth2 up". $ sudo ifconfig eth0 up
eth0: ERROR while getting interface flags: No such device
$ sudo ifconfig eth2 up
$ sudo ifconfig

yeah!
for a reason I that don't understand, udev now renames eth0 in eth2
in 2.6.18, it renamed it in eth1
on my debian, i changed that in: /etc/network/interfaces
thanks a lot Ayaz for showing me the way!
