Subject: Intel TGL notebook no longer enters power states deeper than PC2 (fwd from bugzilla)
Date: Thu, 20 Jan 2022 15:56:38 +0100	[thread overview]
Message-ID: <34eb9d46-d937-fc29-02b1-7cfb9162f9b8@leemhuis.info> (raw)

Lo! There is a regression dealt with in bugzilla I'd like to add to the
tracking:

#regzbot introduced: e5ad96f388b765fe6b52f64f37e910c0ba4f3de7
#regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215467
#regzbot from: MarcelHB <m.heingbecker@googlemail.com>
#regzbot title: Intel TGL notebook no longer enters power states deeper
than PC2

> Summary:
> 
> Starting with Kernel 5.15, my Intel TGL notebook no longer enters power
> states deeper than PC2. Previous kernels did so.
> 
> Explanation:
> 
> On my notebook, I recently started to observed that the battery drained
> quickly while in a presumed suspend mode. In the past, there was no such
> problem.
> 
> I was able to bisect the problem on a tag-basis, analyzing deeper
> information on what looks good and what does not.
> 
> In the short: From somewhere at least v5.11.x until v5.14.21, the
> system operates as expected when closing the lid. Starting with 5.15.0, I observed the anomalies as reported below.

Ciao, Thorsten
