And even stranger, now that I did not enable the printk it happened again. It was sleeping, I touched the pad, power led came on, but screen backlight did not, and it does not respond to keys or touch anymore. Also, it does not go back to sleep according to the power led, so it indeed is frozen I'd say.  Mysterious.
