I've had the same happen on occasion, and won't of course blame pmud for
it :-) Seriously, what seems to happen is the battery is lying about how
much charge is left, and runs out during sleep.
pbbuttonsd and pmud do the same when putting the machine to sleep, no? All
you can blame is the kernel (for failing to actually put devices to sleep,
some of which you can verify for yourself) or the battery.
