The kernel will never trigger a sleep by itself. Only
pmud or pbbuttonsd may. You will want to look at those logs or
track an eventual bug in there.
Ben.
OK, I'll have a look at the pmud code and come back later.

Please try running pmud with the -s or -S flag (signal init on power low)
and take note of the battery power level readings. I suspect the kernel
does return erroneous power readings on occasion, causing pmud to trigger
sleep. I've not been able to reproduce this on my Lombard Powerbook -
other users (iBook IIRC) report the battery power suddenly dropping to
zero from as much as 80%. I'm currently trying to collect more information
on this new feature.

I have a first generation iceBook (500MHz/64MB stock/Rage128
Mobility), and I never see this behavior ... however, I recently
talked my girlfriend into a new iceBook, and the model she got
(600MHz/128MB stock/Radeon Mobility M6 LY) does. It doesn't seem to
be predictable as best we can tell, and it doesn't happen often. It
seems to happen whether the laptop is plugged into wall power or not.
(Does it irritate anyone else that there seems to be no *good* way to
differentiate iBook versions? I'm sure there's some motherboard
resource version that's unambiguous, but come on...)
If I can provide any information that might be useful, please let me
know. I have both of these laptops sitting in the same room with me
pretty much every day of the world for at least some period of time.

Just read the device tree:
/proc/device-tree/model gives you the model name.
/proc/device-tree/scb# gives you the revision number.

I actually meant for the layman ... I realize that I can look up
system resources (in this case OF values) that will tell me, but hand
me an iBook and ask me what rev it is ... no clue.
