ethernet devices are not always detected in same order

Bug Description

My physical ethernet devices are not always mapped on the same device /dev/eth<X>.

My gigabit controller was eth1 :

Aug 3 17:46:59 localhost kernel: [17179590.964000] skge 1.3 addr 0xe5000000 irq 217 chip Yukon-Lite rev 7
Aug 3 17:46:59 localhost kernel: [17179590.964000] skge eth1: addr 00:0e:a6:5c:89:51

and is now eth0 :

Aug 4 17:05:57 localhost kernel: [17179592.128000] skge 1.3 addr 0xe5000000 irq 209 chip Yukon-Lite rev 7
Aug 4 17:05:57 localhost kernel: [17179592.128000] skge eth0: addr 00:0e:a6:5c:89:51

I can provide other traces, if you need.

Here are the extract from lspci showing both interfaces:

Please check /etc/iftab if it has an entry for every card.

Setting package to linux-source-2.6.15, so this bug gets out of the list of bugs without a package.
Can you confirm this bug still happens in edgy/feisty?
Thanks.

We are closing this bug report as it lacks the information, described in the previous comments, we need to investigate the problem further. However, please reopen it if you can give us the missing information and don't hesitate to submit bug reports in the future. (i.e. if bug is still reproducible and output of /etc/iftab)

I'm having this problem in ubuntu 6.06.
I have 2 ethernet cards connected.
An on-board card, and a PCI gigabit card.

The PGI gigabit card keeps jumping from eth1 to eth2.

Will provide further details soon.

lspci.out Edit (15.9 KiB, text/plain)

Other than comments, iftab contains the following line:

eth0 mac 00:1a:a0:3f:78:a1 arp 1

I have also attached the output of lspci -vv
