Is that: commit 0cac73eb3875f6ecb6105e533218dba1868d04c9 Merge: 94df82fe5bfd 350cbb5d2f67 Author: Linus Torvalds Date: Fri Jun 14 09:52:51 2024 -0700 Merge tag 'pm-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/gi= t/rafael/linux-pm =20 Pull power management fix from Rafael Wysocki: "Restore the behavior of the no_turbo sysfs attribute in the intel_pstate driver which allowed users to make the driver start using turbo P-states if they have been enabled on the fly by the firmware after OS initialization (Rafael Wysocki)" =20 * tag 'pm-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/ra= fael/linux-pm: cpufreq: intel_pstate: Check turbo_is_disabled() in store_no_turbo() ? I don't think I tweaking no_turbo in the sysfs. But the thermal stuff looks important: commit cee84c0b003f2e0f486f200a72eca2bcdb3a49a7 Merge: d20f6b3d747c b6846826982b Author: Linus Torvalds Date: Fri Jun 14 09:28:56 2024 -0700 Merge tag 'thermal-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kern= el/git/rafael/linux-pm So I guess I'll have to try again.
