If you have a Zen2 or newer AMD processor, you can use a grubby command in a terminal to set the needed kernel argument: sudo grubby --update-kernel DEFAULT --args "initcall_blacklist=acpi_cpufreq_init" Then, after a reboot, you can use this command to see if it worked: cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver If that says something other than amd-pstate then it did not work, and you can try adding another kernel argument and then rebooting: sudo grubby --update-kernel DEFAULT --args "amd_pstate.shared_mem=1" -- Terveisin / Regards, Matti Pulkkinen _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
