 On an XO-1.5 B3 prototype (#17), running Q3A16 and os45, I had a reboot
 instead of a resume.

 The laptop was modified with the XO1.5 WLAN SR ECO:

     http://wiki.laptop.org/go/XO1.5_WLAN_SR_ECO

 The laptop was set to autowack by adding:

     50 autowack-delay

     autowack-on

 to the olpc.fth file.

 It was associated with an access point.

 From the terminal activity, I enabled EC wakeup events using:

     sudo sh

     echo EC > /proc/acpi/wakeup

 I then started a script (dosr) running:

     for i in seq 1 100000; do echo $i; sleep 1; echo mem >
 /sys/power/state; done;

 After twenty cycles, I stopped it and checked the interface using iwconfig
 and ping the gateway just fine.

 I restarted it, and after ten or so cycles I noticed that the WLAN LED was
 flashing very quickly.  I stopped, and when I typed iwconfig it took many
 second to respond.  This happened repeatedly.

 This is easy to reproduce.
