 this seems to be a new one. testing a simple "ping" wakeup loop with ohm
 autosuspend, I ran into this:

 {{{
 [  574.584813] Restarting tasks ... done.
 [  575.090380] libertas: EVENT: unknown event id 1

 [  594.147674] libertas: SCAN_CMD failed
 }}}
 followed by many more failures.

 At this time, the wifi LED was flashing rapidly and didn't stop.

 A few seconds later, the system tried to autosuspend. It is now in a slow,
 seemingly infinite loop trying to suspend, as all the commands fail.
