You system is a shared memory design not a MSR design. "[ +0.000016] amd_pstate: AMD CPPC shared memory based functionality is supported" This looks like the calltrace: amd_set_max_freq_ratio ->amd_get_boost_ratio_numerator ->->amd_detect_prefcore ->->->amd_get_highest_perf ->->->->cppc_get_highest_perf ->->->->->cppc_get_perf The first error you see is "No CPC descriptor for CPU:1" which comes from cppc_get_perf(). Can you please share your acpidump? It sure seems like a BIOS bug to me. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are the assignee for the bug.=
