AMD APU not saving preferences (Pstate Bug)

[Fabio]

Hi everybody.
I don't know why after i poweroff my computer, cpu(A4 4355M) resets it's preferences. I found that my apu has pstate 6 (900Mhz) and boost states disabled (by default?), so i use TurionPowerControl to enable them (and undervolt a bit pstate 6), but if a poweroff my computer everything resets. If i reboot, instead, everything stays as i set it. I also tried to set everything on boot but i don't know how to refresh cpufreq(whitout reboot) so to use new frequencies in indicator-cpufreq.

Any ideas? Thank you all.

The main problem is that one of the cpu's pstate is not recognized or used.

Status changed to 'Confirmed' because the bug affects multiple users.

So, it looks like there is a problem somewhere else: cpu low state is used, but not 'seen', as cpufreq-apref claims.
None of virtual devices reports 900MHz avalaible, but it works.

Ok! so it works correctly?
