I am running Ibex on a home built with a Biostar GF8200 AM2+ motherboard and an AMD 4850e processor. I have been running the Ibex beta for a while and everything has been pretty good (except that the only way that I can make it install is to install Hardy with all_generic_ide as a boot flag, and then do a dist-upgrade to Ibex) until yesterday. I run the updates through the update manager, and when it rebooted, I had no ethernet device. I booted off of a vestigial Windows XP partition, and it saw the ethernet device, but ubuntu would not. I did a re-install, and hardy saw eth0 right away, but when I did the upgrade to Ibex, it disappeared again. I know that similar problems have been reported with the intel e1000e driver, but this is definitely not an intel chipset. Is there an easy way to fix this?

(I grep'ed /var/log/messages for an eth0 entry, and there was nothing.
I ran lshw -C network and got
network DISABLED
description : Ethernet interface
physical id: 1
logical name: pan0
serial: a2:75:3c:4d:bf:34
Capabilities: ethernet physical
configuration: broadcast=yes driver=bridge driverversion=2.3 firmware N/A link=yes multicast=yes

when I unplugged the cable the link=yes went away

Is it configuring my ethernet as pan0? It looks to me like pan0 is something bluetooth related. Has anybody seen anything similar? Is there a way to fix it?

Could we see the output of lspci -v; lsmod?
