I have an iBook 2 (PowerBook 4,1) and I rsync'd my kernel to
2.4.20-ben7 last night (I had previously been running 2.4.20-pre7-ben0
with no trouble). The lid latch does not seem to put the machine to
sleep any more, and when I put it to sleep with the power button,
waking the machine up shuts it off rather than waking it. I then have
to depress the power button for a few seconds, release it, and press
it briefly in order to power the machine back up.
The machine is not losing its time/etc, merely shutting down.
I'm running pbbuttonsd-0.5.2 in pmud replacement mode.

Can you try -ben4 or -ben5 ? Patches against official 2.4.20
are on kernel.org/pub/linux/kernel/people/benh.
Let me know if it works
Ben.

Hrm... before that, try this patch against -ben7

You're the man, Ben. :-) This patch seems to work perfectly. I
assume you are not interested in the results from -ben4 and -ben5? (I
can still check.)

You assume correctly. I'll release -ben8 early next week with
that fix.
Ben.
