 I am testing suspend/resume of the mwifiex driver using a kernel.org
 linux-3.5.2 kernel on an XO-1.5 with an 8787 dev kit plugged in the
 external SD slot.

 iwconfig mlan0 essid olpcn
 ip link set dev mlan0 up

 i=0 &&
 while sleep 3 ; do
       i=$(($i + 1)) &&
       echo ===== $i =====
       rtcwake -s 6 -mmem
       time ping6 -q -A -c 1000 -I mlan0 fe80::21c:25ff:fe55:6758
       date +'%s --- %a %b %d %H:%M:%S %Z %Y'
 done

 I have seen several complete wedgeups of the machine, where the only thing
 that recovers is holding the power button in.

 Shortly before each wedgeup, I see these sorts of error message from the
 mwifiex driver (taken from 6 different such wedgeup instances):
