https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253288 --- Comment #29 from rkoberman@gmail.com --- (In reply to Ulrich Spörlein from comment #28) The commit is the one that enables P-States and it seems to work fine on all but Lenovo ThinkPads. All that can be done until someone with a lot more ACPI 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=1 to /boot/loader.conf. Since P-State support was not present before 13.0, it leaves 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. -- You are receiving this mail because: You are the assignee for the bug.help
