Comment 55 for bug 842560

@Netmatters I'm having the exact same problem on a HP 360 G5 with Ubuntu Server 64 11.10.

Everything was working fine until Ubuntu Desktop 64 11.04.

During the installation (not an upgrade) of Ubuntu Server 64 11.10, I manually set up a static IP address, gateway, netmask and DNS server for eth0 but in the end no network connection was available as expected.

These are two screenshots taken during boot with a camera:

I will try with the fix from comment #46 and report back.
