I installed Ubuntu on a second, similar, machine, and I am experiencing this bug on the second machine as well.
The two machines are: 1. AOpen MP965 (with x64 Intel CPU) Intel GM965 + ICH8M Chipset 2. AOpen MP945 (with x64 Intel CPU) Intel 945GM + ICH7-DH Chipset Each machine has an onboard ethernet NIC built into it. Each has computer has a fresh install of Ubuntu 10.10 Maverick Meerkat x64. I experience this issue randomly on each machine, and have to try my luck by rebooting to see if eth0 comes up. I have filtered syslog by "eth0" and attached it to this report. Some lines of syslog that I think are relevant are... NetworkManager[1101]: SCPlugin-Ifupdown: devices added (path: /sys/devices/pci0000:00/0000:00:19.0/net/eth0, iface: eth0) NetworkManager[1101]: SCPlugin-Ifupdown: device added (path: /sys/devices/pci0000:00/0000:00:19.0/net/eth0, iface: eth0): no ifupdown configuration found. NetworkManager[1101]: <info> (eth0): carrier is OFF NetworkManager[1101]: <info> (eth0): new Ethernet device (driver: 'e1000e' ifindex: 2) NetworkManager[1101]: <info> (eth0): exported as /org/freedesktop/NetworkManager/Devices/0 NetworkManager[1101]: <info> (eth0): now managed NetworkManager[1101]: <info> (eth0): device state change: 1 -> 2 (reason 2) NetworkManager[1101]: <info> (eth0): bringing up device.

(This is a desktop computer, so there is no on/off switch, as on laptop computers with wireless cards). Also, it seems to be deactivating eth0 with "reason 2." What does "reason 2" mean? The contents of /etc/network/interfaces is... auto lo iface lo inet loopback The contents of /etc/NetworkManager/nm-system-settings.conf is...
