Bug ID: 219981
Summary: Regression on amd-pstate suspend/remove
Product: Power Management
Version: 2.5
Hardware: AMD
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: cpufreq
Assignee: [email protected]
Reporter: [email protected]
Regression: No

The issue that was reported here was solved by adding handlers for suspend/resume events https://bugzilla.kernel.org/show_bug.cgi?id=215938

These handlers has been removed with this commit
https://github.com/torvalds/linux/commit/2064543f5ba0d2929e3e9b3a616c3262a57c7925
and I am suffering the same issue again (so scaling frequencies are ignored after a suspend)

[Bug 219981] Regression on amd-pstate suspend/remove

https://bugzilla.kernel.org/show_bug.cgi?id=219981

--- Comment #1 from Mario Limonciello (AMD) ([email protected]) --- What kernel are you testing with? Does it happen with 6.15rc1 or at least a hash near it with the AMD pstate 6.15rc1 content (at the time of my comment 6.15rc1 not yet posted)

If you can reproduce on 6.15 rc1 please capture a report using this script both at boot up and after resuming from suspend.
