Subject: Fwd: Abnormal battery drain with kernel 6.5 (Ryzen 5500u)
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

Hi,

I notice a regression report on Bugzilla [1] that have been already handled
there. Quoting from it:

> After switching from 6.4.x kernel to 6.5 I experienced an abnormal battery drain since my laptop is actually never idle.
> I accepted default CPUfreq to schedutil and AMD Processor P-State mode is 3 (active). 
> 
> I expected a different behaviour, but am I missing something?
> In my boot configuration I had "amd_pstate.shared_mem=1" and tried to remove this switch, but did not affect my power consuption.
> 
> Is there something changed from 6.4.x to 6.5 that requires a different configuration to get an optimal power consumption?
> 
> Thanks a lot for your attention

See Bugzilla for the full thread.

Anyway, I'm adding it to regzbot:

#regzbot introduced: v6.4..v6.5 https://bugzilla.kernel.org/show_bug.cgi?id=217853

Thanks.
