APIC, ACPI, IOAPIC, enabled or disabled.. lots of different kernels soltek frn2 nforce2 based board, barton XP 2500+, 512mb ddr Bios doesn't allow disabling of stop grant, but I've tried both states with athcool.
It's really entering the stop grant state, because when completely idle it makes a measurable heat difference. (though when playing mp3s, almost all of the cooling benefit is lost)
This machine hasn't crashed yet.
If there's something I can do to crash it so I don't feel special anymore, or if there's some way I can provide useful information, let me know.

I hope my email wasn't interpreted as an attack on the patch. I think getting linux running on flakey hardware without any support at all from the manufacturer is incredibly cool. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
