Public bug reported:
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:
