I actually have the original, stock SD card of the original device somewhere. I'll probably try to reproduce the issue on that, to see if there's a stock firmware, SD card or hardware problem...

The wake is failing possibly because of whatever happens above. It might also depend on if you close the cover after putting it to sleep. To test some of this, I would disable the sleep when closed option.
That's a great idea, i'll give that a shot as well. I figured the "lid close" sleep was the same as the sleep button, but who knows...

That's the thing that's weird with this bug: the "20 second hold" trick just doesn't work when it crashes that way. The power led blips *once* early after pushing, and then nothing happens, it doesn't actually turn off (or, to be more specific, back on: it's hard to tell it's off in that case...)
