The last time it happend is a few weeks ago, but at least on my PowerBook6,8 it
only happend when the fan had spinning at full speed for some time (due to high
CPU usage, so it was ok that the fan was spinning so fast). I considered this
a feature of the firmware (?) that did some emergency stop once the fans weren't
able to do their job successfully anymore.
Yes, now as you say it, I can confirm this for an iBook G4. I had the
same problem with high CPU load. The fan starts spinning and increase
its speed until it runs very fast. Then it starts to pulse (increase
speed -> decrease speed -> inc...) and after a minute or so the iBook
powers off

I've run pbbuttonsd and cpufreqd to scale the CPU.
strange...
I'm a gentoo-user and compiling frequently, but my iBook (G4,1.2GHz, got
it Feb05) never dies on _high_ cpu load.
it happens mostly when I'm typing some stuff in vim or composing
mails/forum posts, many open rxvts, running firefox, opera,
thunderbird, xchat, maybe mpd, but the cpu is still 80%+ idle.
I got the feeling, it's more frequently with some pbbuttonsd versions,
but I'm not sure... sometimes I try a new kernel release and the system
powers of three times this day, then runs stable for over a week...
I'm not running a daemon for cpu frequency, setting it manually when I
need the power.
my current kernel is 2.6.14-gentoo-r2 and I'm running pbbuttonsd 0.7.2.
well, and:
