sleep with ibook G4 (july05-modell)
i played around with suspend-to-disk and suspend-to-ram. suspend-to-disk
works very fine on my new ibook, but i have still problems with
suspend-to-ram. i try it manually with
echo "mem" > /sys/power/state
and with the hibernate package.
I test nearly all settings in pbbuttonsd and also replaced it with pmud.
pmud dont run, reporting:
root@book:~# pmud -d -n
pmud: pmud [treshold = 420, margin = 15] started
pmud: opening /dev/adb
pmud: opening /dev/pmu
pmud: pmu_op(0xea, ..., version req)
PMU version 12: iBook/G3 Pismo/G4 Titanium
pmud: PMU version 12: iBook/G3 Pismo/G4 Titanium
pmud: No sleep support on this hardware, exiting!
pmud: daemon stopped (missing sleep support)
when i set up hibernate.conf with
and run hibernate (or manually with echo "mem") my computer seems to do
everything what it should do before and afrer it "fell in sleep"
instead of sleeping it self. from /var/log/debug:

I am also confused by the output, when pbbuttonsd starts:
Restarting pbbuttonsd: pbbuttonsd 0.7.1: iBook/G3 PB Pismo/G4 PB
Titanium (PMU version: 12)
Is this ok? Or is my laptop detected as a wrong model?
Is there somebody with a _new_ ibook G4 from july2005 (or later) with
working suspend-to-ram? Because i got some well-meant feedback from
users with the ibook G3 or the older ibook G4 from 2004 i will emphasise
that I have a newer modell, which is different (remember touchpad and
sound problems, maybe pmu or similiar have also changed).
If somebody has an working sleep on this model maybe i just have a
non-working configuration or use the wrong tools. Else maybe this is a
bug or missing feature, which should reported to somebody (unfortunately
I am not a programmer to fix it).
I am also interest in tips how to debug this issue better.
the only thing i missing from the x86-world is ACPI, but maybe I am
familiar with PMU soon. :-)
P.S.: Maybe this additional information is helpful:
