[Bug 580548] Re: Atheros 8121 OnBoard Ethernet Adapter worked on 9.04, but doesn't work on 10.04

[Yaniv Aknin]

I also encountered this bug, and it was rather confusing, let me add my 0.02$:
 - I'm running 10.04, upgraded from 9.10 upgraded from 9.04
 - The symptoms are no eth0 *and no listing of the network adapter in lspci* (?!)
 - Rebooting didn't help, I found atl1e inserted, rmmodded it and tried adding atl1c and atl1e to no avail (nothing in dmesg)
 - Rebooting to a USB stick (Ubuntu 9.10) suddenly fixed the problem, I also noticed atl1c is loaded (instead of atl1e)
 - After I rebooted back to 10.04, the problem disappeared, atl1c was loaded and my adapter appeared in lspci as usual.

I'm not sure what to make of the facts, but not quite in a condition to
look into it any further, make what you will of this.
