Sounds similar to what I ran into this morning. I tried to power down the device last night by holding the power slider for several seconds while on the home screen (but didn't get the power off prompt) and then when I let go it apparently went to sleep (and stayed asleep finally) but when I woke it this morning it was on a white screen. Had to reset to get it working again. I'm running the 10-07-05 firmware (that apparently isn't on the PD site yet).I'm really hoping that Pandigital supports their device and keeps plugging away at fixing the bugs. It has a lot of potential and really is a neat little slate.
