Comment(by Quozl):

 Overnight tests here:
  * XO-4 B1 SKU293 with 8686, did not reproduce over 18 hours,
  * XO-4 B1 SKU292 with 8787, reproduced after 6 hours,
 http://dev.laptop.org/~quozl/z/1UhRm5.txt
  * XO-4 C2 SKU306 with 8787, reproduced after 10 hours, no serial cable
 mounted.

 Confirming the reproducer:
 {{{
 fs-update u:\32007o4.zd
 boot
 rpm -i kernel-3.5.7_xo4-20130523.1701.olpc.36da52f.armv7hl.rpm
 touch /runin/{soiled,force}
 reboot
 }}}

 Environment is two APs beaconing an 802.11g ESSID "qz", with one of them
 beaconing an 802.11n ESSID "n" on 5GHz only.  Regular traffic with the APs
 from other systems.

 ''ifconfig'' is used frequently in the ''runin-wlan'' test.
