eth0 disappears after reboot/full shutdown

shannonbay · 03-29-2009, 03:57 AM

I have a strange question - why does my onboard ethernet card sometimes disappear after a reboot, or more rarely (it seems), a full shutdown? This is without changing any software settings.

Sometimes I get this:

Code:

root@atomant:/home/shannon# lspci | grep -i Eth
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express (rev 01)

and other times I get this (regardless whether I search for eth or net):

Code:

root@atomant:~# lspci -v | grep -i Eth
(nothing)
root@atomant:~# ifconfig eth0
eth0: error fetching interface information: Device not found
root@atomant:~#

I would install 12.2 and that will probably fix it.

Maybe the firmware for the BCM5751 has not been loaded?

You were right... a mate of mine got me a copy of 12.2 and I've just finished installing. No problems with ethernet now.
