[Bug 55197] ethernet devices are not always detected in same order

[Jeremy Vies]

You have been subscribed to a public bug:

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:
