Subject: Fwd: System (Xeon Nvidia) hangs at boot terminal after kernel 6.4.7

Hi,

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

> Kernel 6.4.6 compiled from source worked AOK on my desktop with Intel Xeon cpu and Nvidia graphics - see below for system specs.
> 
> Kernels 6.4.7 & 6.4.8 also compiled from source with identical configs hang with a frozen boot terminal screen after a significant way through the boot sequence (e.g. whilst running /etc/profile). The system may still be running as a sound is emitted when the power button is pressed (only way to escape from the system hang).
> 
> The issue seems to be specific to the hardware of this desktop as the problem kernels do boot through to completion on other machines.
> 
> A test was done with a different build (from Porteus) of kernel 6.5-RC4 and that did not hang - but kernel 6.4.7 from the same builder hung just like my build.
> 
> I apologise that I cannot provide any detailed diagnostics - but I can put diagnostics into /etc/profile and provide screenshots if requested.

See Bugzilla for the full thread.

FYI, this is stable-specific regression since it doesn't appear on mainline.
Also, I have asked the reporter to also open the issue on gitlab.freedesktop.org
tracker (as it is the standard for DRM subsystem).

To the reporter (on To: list): It'd been great if you also have netconsole
output on your Bugzilla report, providing that you have another machine
connecting to your problematic one.

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

#regzbot introduced: v6.4.6..v6.4.7 https://bugzilla.kernel.org/show_bug.cgi?id=217776
#regzbot link: https://forum.puppylinux.com/viewtopic.php?p=95733#p95733

Thanks.
