Try to enable mac80211/cfg80211 debug messages. Also enable SSB
debugging. (If mac80211 debugging is on, then you are hitting a
{mac|cfg|nl|lib}80211 bug, as your dmesg should contain entries like
"device is no longer idle".)

To Larry: Software RFKILL is not yet implemented for LP-PHY - it is
part of my calibration patch, which had other errors (software RFKILL
is a prereq for calibration). Feel free to split it out into a
separate patch if anyone needs it - I can't do it right now; no
working Linux system (due to the vmware problem).
