Summary: CPU Frequency scaling jumps and stucks at max freq
Product: Power Management
Version: 2.5
Kernel Version: 4.5
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: cpufreq

config of bisected kernel
Switching to 4.5 kernel, cpufreq ondemand governor started to act oddly.
Without any load, with freshly booted system, it pumped cpu frequency up to
maximum at some point of time and stayed there. uptime can be anything, but
usually less than 15 minutes when this happens. Driver is acpi-cpufreq.
I have git-bisected this to 0df35026c6a527e65b53bc895ad672d648a248f3. There is
a mention about certain kernel config values that are ok. My values differ and
I get this kind of behaviour.
CPU is AMD Phenom(tm) II X4 905e Processor.
