I'll push that out to Linus along with a large bunch of other cpufreq changes tonight/tomorrow. Strange how your CPU seems to claim to support voltage scaling, but erm.. doesn't. Can you also mail me the output of x86info -a -v (Get the snapshot from http://www.codemonkey.org.uk/cvs/ ) > longhaul: MinMult(x10)=30 MaxMult(x10)=60 > longhaul: Lowestspeed=0 Highestspeed=0 > longhaul: FSB:0 Mult(x10):100 Something also went horribly wrong when trying to determine your FSB. > divide error: 0000 [#1] Leading to this tradegy. I'll take a look over the longhaul code later too, as it could use some cleanups in more than a few areas. I've also fallen behind in adding support for the newer C3s to it. Dave
