Re: G3 iBook resume kernel oops - help appreciated.
On my ibook2.2, G3 800, no problem. I use alsa but neither pbbutton nor
powernowd (only cpufreqd).
I use pmud and I have the following pwrctl-local, a file which is read
by pmu when sleeping and awaking.
It maybe related to pbbutton, which try to access the mixer too early
# save and restore sound setting (get confused during sleep)
case "$1" in
wakeup) aumix -f /etc/aumix -L ;;
sleep) aumix -f /etc/aumix -S ;;
