Relevant syslog when the disconnect occurs. This seems to happen more or less randomly, I'm not doing anything in particular when it happens.

I've found that I experience the bug when I connect via NetworkManager, but if I shut off NetworkManager and invoke wpa_supplicant directly, the problem does not occur! So somehow it has to do with NetworkManager's use of wpa_supplicant.
