If i swap back to the 7.0 kernel using the kernel manager performance mode works fine again, if i set my mode to performance in 7.0 a= nd then boot back to 7.1-rc i get that same weird half broken frequency limiti= ng thing where it won't go past 3.0Ghz until i go back to balanced, but then g= et the communication GDBus error trying to go back to performance again. =E2=9D=AF cat /sys/devices/system/cpu/amd_pstate/status active ~ =E2=9D=AF cat /sys/devices/system/cpu/amd_pstate/dynamic_epp disabled ~ =E2=9D=AF cat /sys/devices/system/cpu/amd_pstate/prefcore enabled This is a pretty standard desktop computer, no battery involved and nothing ASUS.
