Either you dont have it > working correctly or it doesn't work at all in your case. It is working somehow, and the 2 degrees are significant in my case, because the 45°C is pretty stable in unloaded state with apm enabled. Tmax is around 48°C when compiling kde, transcoding divx or the like. As noted in another message here, I'am going back to apm because it appears that vlc became sluggish (& back to 45°C CPU base temp. & ~15% base load from apmd-idled, I bet :) > > You also need acpi idle calls, not just apm. now this is just my guess > but apm idle calls might either mess things up or be disabled if acpi > idle calls are used and disconnecting the cpu... either way you can't > have this patch work and apm work at the same time. I know, and I think Daniel should have noted that one have to disable APM to get ACPI power savings work. Would have saved me one reboot.. Cheers, Hans-Peter
