One theory would be that the clock gets shut down while the VT is
being cleared character by character. There's some kind of logic
like this in the console/VT/FB subsystem, but it's spread out over
a lot of code. Anyway, the clock isn't the problem.

I left the device sit for a few hours and nothing interesting
happened. Then I disabled and re-enabled the LCD clocks one by one
but this just made the LCM content decay (and to recover when I
turned the clocks back on), not yielding the pattern I had

Well, maybe it'll decide to happen overnight. I'll take a picture
and try the power button if it does.
