Re: Regression on 5.19.12, display flickering on Framework laptop

Hi, this is your Linux kernel regression tracker.

A bisect would be good, as Greg already mentioned.

Not my area of expertise, so it's a wild guess, but display flickering
made me wonder if this change is the culprit:

https://lore.kernel.org/all/20220926100814.131449678@linuxfoundation.org/

If it is, simply starting with "i915.enable_psr=0" might already help.
but as I said, just a wild guess after briefly looking into the problem.

Anyway, for the rest of this mail:
[TLDR: I'm adding this regression report to the list of tracked
regressions; all text from me you find below is based on a few templates
paragraphs you might have encountered already already in similar form.]

Thanks for the report. To be sure below issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression
tracking bot:

#regzbot ^introduced v5.19.11..v5.19.12
#regzbot title Display flickering on Framework laptop
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply -- ideally with also
telling regzbot about it, as explained here:
https://linux-regtracking.leemhuis.info/tracked-regression/

Reminder for developers: When fixing the issue, add 'Link:' tags
pointing to the report (the mail this one replies to), as explained for
in the Linux kernel's documentation; above webpage explains why this is
important for tracked regressions.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
