Public bug reported:
Binary package hint: linux-source-2.6.22
I just installed Gusty with kernel 2.6.22-12.
During the installation two ethernet cards were detected in the machine
as eth0 and eth1 (and there are only two). I used eth0 to install the
system. Upon rebooting /etc/network/interfaces had eth0 configured as I
specified in the installer. However eth0 (and eth1) do not exist. They
are both e1000 supported cards and the e1000 driver is loaded. For some
reason both eth0 and eth1 are detected as such, however the actual
interfaces the kernel sees are eth2 and eth3
