It was killing dsme that did it for me; dsme was continually restarting something (I forget what, now) and following up the chain, I eventually killed dsme triggering the watchdog (I think). To be honest I wasn't watching the device, but working remotely from another room, so I'm not sure what happened on the screen. But as soon as I killed it, it rebooted.

Reads up on dsme..

Actually ... I'm not sure I understand how dsme differs from the standard /etc/event.d asynchronous service daemon. Does anyone have a good link to more thorough documentation?

Edit: Actually, found some here: http://wiki.maemo.org/Documentation/...ity_.28DSME.29

Interestingly, they mention thermal management. I didn't know there was any.
