Well, that didn't work.

I wasn't quite methodical enough.  It depends on my doing something...
it might be the lid switch, or using the sound, or network, or switching
from battery to AC, or removing the battery...

So it needn't be a regression from the patches I tested before.  More
likely it's a problem with certain action(s) that I've only performed
recently.
