 Following range and coverage tests, unit QUOZL 1 has three hung iwconfig
 processes, in D state.  Total uptime 1hr 46min.  During the range test,
 there were several instances where coverage to the access point was lost,
 as expected.  So there have been several loss and restoration of
 connectivity events.  The other two units aren't affected in the same way,
 but they underwent similar travel.  iwconfig was being run twice a second
 to obtain signal and noise levels for logging.  The hang happened shortly
 after the unit was brought back to base and plugged in to the AC adaptor.
 /var/log has been captured to a USB disk.
