Is your essid set to "" (aka. any)?  This is invalid in master mode and
I've found the hardware gets very sick if you have it "" in any mode other
than managed.  If you do an "iwconfig wlan0 essid test" and then go into
monitor mode it should work fine.  I suggested a while ago that some sort
of safety be put into the driver to prevent you doing that.
