Hi Arek:
Could you upload the dmesg log with below parameter in grub?
cpufreq.dyndbg=+p amd_pstate.dyndbg=+p cppc_acpi.dyndbg=+p debug loglevel=8
log_buf_len=100M
If the driver was loaded, I would like to see if there is any loading error.
also need you help to post cpupower output .
# sudo cpupower frequency-info
Perry.
