Is that:
commit 0cac73eb3875f6ecb6105e533218dba1868d04c9
Merge: 94df82fe5bfd 350cbb5d2f67
Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>
Date: Fri Jun 14 09:52:51 2024 -0700

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)"
* tag 'pm-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/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

Merge tag 'thermal-6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
So I guess I'll have to try again.
Thanks and best regards,
Pavel
