Sorry about the delay in getting back to you, it took me a few days to
finish collecting the results, in between furious bouts of Little Big
Planet-ing.

The scenarios I tested were as follows:

1 FAIL: both managed by NM, on the same segment
2 SUCCESS: wlan0 managed by NM, eth0 unplugged
3 FAIL: wlan0 managed by NM, eth0 manually configured, connect to
different segments
4 SUCCESS: both manually configured to different segments
5 SUCCESS: both manually configured, connecting to the same segment

I've not analysed the logs in detail yet, but it appears the problem
only occurs when NetworkManager manages the wifi connection and eth0 is
already connected to any network.

Also, my wifi network uses WPA1, I've checked and the same problem
occurs using WPA2.

I also noted an out of memory exception coming from an ioctrl call when
running wpa_supplicant manually after logging in, but I need to go back
and collect a log of that, as I ran out of time.

Any insight you can give on the problem would be greatly appreciated.

Cheers

Dan
