I did not see an option to disable over clocking, but did disable C-states and made sure turbo boost was enabled. On cold boot the system is fine. The cores fluctuate between 1200 and 3400 Mhz as expected. But on a normal reboot they appear to be locked at 1200 Mhz and never accelerate. Additionally, apps like ps and htop show all processes with a CPU usage of 0%. I can increase the speed by doing a "cpupower frequency-set -g performance", but all processes show 0% CPU usage which is not correct for the apps I'm running. -- You are receiving this mail because: You are the assignee for the bug.
