Hang also present in linux-image-3.7-trunk-686-pae.
sysrq do not work if hangs. Work only "Fn+<>" - keys for increase/decrease brightness, that is strange.
iw event -t shows nothing - output file not created (it has a null size).
If I press in wicd-gtk "Switch off Wi-Fi" and immediately press "Disconnect All" system hangs (on kernel linux-image-3.7-trunk-686-pae).
