All that can be done until someone with a lot more AC= PI and kernel knowledge that I figures it out. Until then, the ony "solution" = is to disable P-State support by adding hint.hwpstate_intel.0.disabled=3D1 to /boot/loader.conf. Since P-State support was not present before 13.0, it le= aves you no worse off than you were on older versions of FreeBSD. Reverting the commit would simply turn off P-State support for everyone and= it is a valuable power management capablity. --=20 You are receiving this mail because: You are the assignee for the bug.=
