XO-1.5 unexpected reboot within OFW associated with autowack resume testing

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:
The laptop was set to autowack by adding:
to the olpc.fth file.
It was associated with an access point.
From the terminal activity, I enabled EC wakeup events using:
echo EC > /proc/acpi/wakeup
I then started a script running:
for i in seq 1 100000; do echo $i; sleep 1; echo mem > /sys/power/state; done;
On the first resume, it did the +r+r+X+Forthmacs rumba.
I have seen this once before, on a laptop without the XO1.5 WLAN SR ECO. At that time, I attributed it to MPPT experiments ongoing with that motherboard. The symptoms, however, are identical and this motherboard has no modifications to enable MPPT.
