I have a t8100 cpu, running gentoo, I've tried both kernels 2.6.29 and 30, but for no avail.
I have 4 stepping: 2.10 GHz, 2.10 GHz, 1.60 GHz, 1.20 GHz but under all governors, the max freq is 1.2 it changes here and there: cpufreq-info shows this:

the range keeps changing, due this thing, it took e 6 and a half hours to compile openoffice, almost twice than the average time that I have compiled it before.
most of the time, the computer is unusable.I have no idea what else can be done, I've checked the bios, all ok, that is the latest version of bios, running boinc, compile and checking for broken libs keeps the freq at min...
I have no idea what to do.
I would appreciate the help.
