The governor "userspace" may decide which speed to use within this range. current CPU frequency is 2.20 GHz (asserted by call to hardware). analyzing CPU 1: driver: powernow-k8 CPUs which need to switch frequency at the same time: 1 hardware limits: 1000 MHz - 2.20 GHz available frequency steps: 2.20 GHz, 2.00 GHz, 1.80 GHz, 1000 MHz available cpufreq governors: conservative, ondemand, userspace, performance current policy: frequency should be within 1000 MHz and 2.20 GHz.

I've seen a few general protection faults. It locks even with the userspace govenor and an attempted manual frequency change. The problens cease when I recompile without SMP, however, this is not really a solution. I'm not a developer, and was hoping someone would be able to help me debug this. I'm running 64 bit Gentoo 2.614 kernel Mark
