For you it’s fine with suspend / resume but fails for hibernate? Can you please use amd-pstate from amd-debug-tools to capture 3 reports.
- Startup
- After Suspend to idle (s0ix)
- After Suspend fo disk (hibernate).
Thanks Mario!
That’s right, after suspend the state is kept at balanced, but after resume from hibernate it’s back to performance mode — and same thing with gnome — it’s not showing that the perf mode is on — but cpufreq does, that and the laptop gets a lot hotter.
Will try and get you the reports.

@Mario_Limonciello I can test the new patch, if we can get the new patch into Fedora kernels like last time. (I just noticed that Gnome on Fedora 42 has a “hibernate” option).
Looks like it wasn’t pulled into 18-rc1 yet LKML: "Rafael J. Wysocki": [GIT PULL] Power management updates for v6.18-rc1 ?
It doesn’t have public review or testing results.
Oh, so it won’t get pulled until there’s feedback from testers ?
@Fn1 We’re the testers, as in specifically you and me.
Suggest to follow the same process as done for the previous patch. That is:
(1) build the kernel with the proposed patch (or request to have someone else to build the kernel for you with the patch, such as Fedora kernel maintainers),
(2) test the patched kernel to make sure it works as intended,
(3) report the result on the appropriate LKML mailing list as a reply to Mario’s email containing the patch.

This has now landed into 5.17.6, I verified that it works. Thank you, Mario!
