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

[Bagas Sanjaya <bagasdotme@gmail.com>]

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.

> During shutdown/reboot console outputs:
> 
> "Failed to umount /oldroot..."
> "kvm exiting virtualization..."
> 
> but cannot complete the process (waited for more than 1 hour).

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.
