It looks like the disconnections are initiated by NetworkManager, which gives the reason 'ip-config-unavailable'. Maybe some kind of dhcp problem, I'm not sure. Right now it isn't looking like a driver problem but something higher in the stack, so I'm updating the bug to affect network manager so that someone more familiar with that level of the network stack can take a look.
