Status: NEW
Severity: normal

Hi.
Since the 3.7.3 kernel, the cpu recognition bug [AMD Phenom II X4 965 B=
lack
Edition @ 3.4 GHz].
-> /etc/conf.d/cpupower :
governor=3D'ondemand'
min_freq=3D"0.80GHz"
max_freq=3D"3.39GHz"
-> cpupower frequency-info
analyse du CPU 0 :
pas de pilotes cpufreq reconnu pour ce CPU
boost state support:
Supported: no
Active: no
My cpu is no longer recognized and freq stay stuck at max.
But, after a few minutes (more than 20) or a few hours my cpu is again
recognized...
-> cpupower frequency-info
analyse du CPU 0 :
pilote : acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 4.0 us.
