Ah, that's so lovely, thanks Jung-uk; I feel that our support for AMD fam. 15h CPUs is lacking. E.g. only four P-states are reported for my A8-5550M, while it supports boosted P-states per BKDG, and reading MSRs directly via `sysutils/amdmsrtweaker' reports eight of them (P0 .. P7), with three turbo P-states P0 P1 P2. Since you have A10-6800 you might try to reproduce what I see here with A8-5550M. ./danfe
