I just had 2.2.18pre17-benh1 running (and sleeping) for about a week on
my Lombard, this morning it simply powered down and reset pram when I
tried to wake it up (battery was 95% full).

I though that was fixed for a long time... weird.

Thought so, too. This was the only time this happened to me since then,
but Albrecht seems to have the same problem.

I also noted some other problems with sleep, mostly irregularly:

xscreensaver tends to become somehow disconnected from the display, when
	this happens, it will run in the background after wakeup and begin
to consume 90%+ cpu, but doesn't blank the screen. It can be
easily killed, however.

Yup. Fortunately, even if you don't kill it, it tends to stop playing the
CPU hog after a few seconds (or minutes ?)

Rather minutes. I didn't remember it ever spinning down on its own
(before I killed it, that is), and I certainly sometimes only noticed it
after 15-30 minutes.

I added some lines to pwrctl-local to kill it before sleeping
and relaunch it afterwards, but even then it happenened once again
(before, it was about every other time, though)

power consumption during sleep is occasionally (not frequently) 5-10
times the normal rate, which will discharge the battery within
24-36 hours.

Bizarre... The new sleep code is supposed to be a lot less robust to
those various issues. Well, I suggest you try again with pmac-stable once
the ADB problem is ironed out. Both Paul and I did various fixes to the
sleep process.

Again, this only happened once with newer kernels.

Thanks,
