Hi,
On my desktop Zen 3 (Vermeer) system applying this series yields a new
warning message on each boot:
Oct 16 06:20:41 kernel: Could not retrieve highest performance (-19)
As I see it, this is one of the pr_debug()s newly promoted to warnings.
Is there anything I can provide to help fix this?
Open up a kernel Bugzilla and attach a full dmesg and all details. You
can CC me directly to it and I'll look into it.
Also ideally; can you please check 6.12-rc3.
Just for completeness:
