--- Comment #17 from Rory A
As a side note I am able to make the system 'more usable' by booting into the working powersave move then adjusting the min CPU MHz values thus speeding up the CPU.
echo 1200000 | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_min_freq
Then when I'm done with whatever CPU intensive task I slow it back down.
echo 800000 | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_min_freq
Sidenote to others trying to make their system usable while trouble shooting this - booting with intel_pstate=disable gives driver acpi-cpufreq, and it does not respect any limits I manually set like this echo 1400000 | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq But if I boot with intel_pstate=passive I still get the driver intel_cpufreq which will respect these limits AND let me use 'powersave' to idle the cpu. Sorry if this is too offtopic for the bug report. Trying to help other people coming from Google. -- You are receiving this mail because: You are on the CC list for the bug.
