http://dev.laptop.org/ticket/10207 has the recipe to make suspend work on XO-1.
(delete the "a" from "ethtool -s eth0 wol ua" in /usr/sbin/powerd)
So I've been testing it.
It works most of the time, but occasionally wakeup from WiFi stops working.
I know about wakeup on arp not working. I can work around that by hardwiring that slot into the arp cache on my PC.
I saw it stop working a couple times a few days ago. I think the WiFi LED was still on, but I'm not sure. I'm pretty sure it recovered when I poked the touchpad. This would match arp not working, but I had the cache setup... Mumble. Both times happened while I was ssh-ed in.
I've got a stuck case right now. That was after working fine
for several days of light traffic. (I'm running a fake ntpd server so I can monitor the clock. So it's the XO is seeing the UDP equivalent of a ping every 5 minutes from two sources.)
The WiFi LED is off. It blinks when I wake it up by poking the touchpad, but the LED stays off and ping doesn't work.
ifconfig says eth0 and msh0 are up. I've grabbed a copy of /var/log/messages but I don't see anything interesting in there.
