Subject: Fwd: amd-sfh module causes reboot and shutdown hangs randomly on hp
 aero 13

Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> My laptop (hp aero 13-be0024t) hangs at reboot and poweroff requiring physical poweroffs (long pressing the power button) when attached dmesg output is generated. But this seems to be random as sometimes I have a dmesg with no errors related to amd_sfh and I can cleanly reboot/poweroff. Blacklisting amd_sfh module fixes the problem. This problem started with kernel 6.2.x and still present in 6.5.2.

See Bugzilla for the full thread and attached dmesg output for both hanging
and no hanging conditions.

Anyway, I'm adding this regression to be tracked by regzbot:

#regzbot introduced: v6.1..v6.2 https://bugzilla.kernel.org/show_bug.cgi?id=217900

Thanks.
