Well, I hate to say it, but it seems, it doesn't work, or at least not so well, (running hot, but stability seems to be there) with 2.6.3-mm2. Like I had 52°C mostly idle with your patch and APIC just a few moments ago. Now back to PIC within a few minutes I am back to 45°C...7°C is too much of a difference for me. To be honest, I can't remenber how it was with the older kernel and I haven't tested temp of apic_tack patch with 2.6.3-mm2, but for the moment I am back to PIC. (My CPU is running at 11x200MHz, 1,7vcore btw.) Cheers, Prakash
