The system is a headless debian squeeze with a self build vanilla 2.6.39
kernel. The network is handled by debian scripts I just added the following
to /etc/network/interfaces:
auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

No NM involved.

Sorry, I don't have the output at hand but IIRC basically nothing special
occurred in dmesg. The interface even keeps it's IP although the wireless
was long gone.

Sure, just let me know what to test.

Ccing Ali Bahar to this reply, since he has seen something similar.
Ali, if I can help with testing please let me know. And no rush in case
you're busy with something else atm. I appreciate the help.
