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 thought the firmware caused the shutdown due to a too high temperature, but if I hear you, it makes me wonder. I think I could reproduce this, but it happened some times ago. Since then I pay attention on the CPU load and run programs like firefox with nice to make cpufreqd do not speed up the CPU. $ cat /proc/cpuinfo processor : 0 cpu : 7455, altivec supported clock : 606MHz revision : 0.3 (pvr 8001 0303) bogomips : 610.30 machine : PowerBook6,3 motherboard : PowerBook6,3 MacRISC3 Power Macintosh detected as : 287 (iBook G4) pmac flags : 0000001b L2 cache : 256K unified memory : 640MB pmac-generation : NewWorld I've run pbbuttonsd and cpufreqd to scale the CPU.
