I may confirm this, I got unexpected "wow" events (it was already
reported), playing with enabling/disabling wifi in FSO after a bit put
the wifi chip in an unusable state with a strange framework log error
(similiar to expecting power set to 0 but failed), when this happens
the command "iwconfig eth0 power off" crashes and the kernel oops.
Other problems with wpa roaming mode that seems to not work,
wpa_action is missing, wpa_cli does not reports all connect/disconnect
errors and so on.
I ignored all these issues as before I used mainly BT networking and
USB, they works well with recent kernels, with olders BT stopped to
work after suspend/resume and with USB my laptop was often not able to
The network nightmare :)
