after upgrading to Fedora 33, my CPU is stuck to 400MHz and the overall performance is really slow. When I run
$ cpu-power frequency-info
analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 2.00 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 2.00 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 400 MHz (asserted by call to kernel) boost state support: Supported: no Active: no
tlp to make sure, that the error does not originate from these packages. I’m using Fedora with my laptop since four years and never had a problem with the cpufreq settings.
The laptop model is an ASUS R541U with an Intel Core i3 CPU (nothing exotic ;-)).
Any hints? Thanks in advance!
