I missed that, true, now i run not patched STABLE. However, my problems remain: 1. With cpufreq framework, I tried powernow module (with powerd of course). Problems: a) sometimes powerd 'misses' the temperature jumping from somewhere near _PSV to over _CRT resulting in system shutdown. - I tried to change the interval time but it didn't help much, I'll try to check it better though. - I tried to lower the _PSV value somehow, but I cannot -- either with sysctl or asl acpi tweaking. - I tried to set ACx levels to better cool my cpu, but failed to set them (they are all set to -1 and no mention of them in the acpi asl) b) when the system is idle, and the temp is about 47-55 degrees Celsius, the acpi_ppc module seemed quieter (it turned off completely i guess). powernow modules is running fan at lowest, but still audible and quite distracting level 2. With acpi_ppc, the cooling is well driven, but acpi_ppc does not throttle cpu when _PSV is hit resulting in _CRT shutdown. - I think acpi_cnq (as acpi_ppc to cpufreq port) would join acpi_ppc's fan-driving and cpufreq passive cooling, but It panics on kldload (a bad free). - Is acpi_cnq integrated obsoleted by powernow module?
