Comment 18 for bug 130665

I'm having the same problem with linux-restricted-modules-2.6.24-19-generic.

I have to add that there's something weird going on. In the network manager applet I only see the ppp0 and eth0 device (ath0 is missing). I decide to reboot hoping that would fix the problem, but after reboot I only see ppp0. eth0 has also went missing.

A soft reboot of my laptop didn't make eth0 return.
Also a soft reboot with kernel 2.6.24-16-generic, did not make my eth0 return, however my wifi does work.

A hard reboot did make eth0 return.
