Summary: CPU recognition bug for AMD
Product: Power Management
Version: 2.5
Kernel Version: 3.7.4-1-ARCH
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1

Hi.
Since the 3.7.3 kernel, the cpu recognition bug [AMD Phenom II X4 965 Black
Edition @ 3.4 GHz].
-> /etc/conf.d/cpupower :
governor='ondemand'
min_freq="0.80GHz"
max_freq="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.
limitation matérielle : 800 MHz - 3.40 GHz
plage de fréquence : 3.40 GHz, 2.70 GHz, 2.20 GHz, 800 MHz
régulateurs disponibles : ondemand, performance
tactique actuelle : la fréquence doit être comprise entre 800 MHz et 3.40
GHz.
Le régulateur "ondemand" est libre de choisir la vitesse
dans cette plage de fréquences.
la fréquence actuelle de ce CPU est 3.40 GHz.
boost state support:
Supported: no
Active: no
