Subject: [regression] Bug 218641 - Framework Laptop 13 AMD suspend/wakeup
 regression with 6.9rc1

Hi, Thorsten here, the Linux kernel's regression tracker.

Anna-Maria, I noticed a regression report in bugzilla.kernel.org that
apparently is caused by a change of yours. As many (most?) kernel
developers don't keep an eye on it, I decided to forward it by mail.

Note, you have to use bugzilla to reach the reporter, as I sadly[1] can
not CC them in mails like this.

Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=218641 :

See the ticket for more details and additional comments.

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

[1] because bugzilla.kernel.org tells users upon registration their
"email address will never be displayed to logged out users"

Everything you wanna know about Linux kernel regression tracking:

If I did something stupid, please tell me, as explained on that page.

P.S.: let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:
