After manually applying just "[PATCH v2 10/10] cpufreq: amd-pstate: automatically load pstate driver by default" to 6.6.31, the AMD Ryzen 3 4100 system is no longer crashing at bootup with X86_AMD_PSTATE_DEFAULT_MODE set= to 1 (Disabled) and when no amd_pstate option is specified. --=20 You may reply to this email to add a comment.
