Well done!

This is great :-)

Yeah, there are some improvements to be made for the procedure.

You're welcome and thanks for doing this.

1) Now you get to brag to all your family and friends that you build a Linux 
kernel :-D
2) The commit that Bjørn identified also contained a "Link:" tag:
https://lore.kernel.org/r/20230105041059.39366-1-kvijayab@amd.com

The best thing to do is to respond to that thread and explain the issue you 
ran into. At the bottom of the page you can find instructions on how to do 
that. The To/CC list is quite large, but don't be alarmed by that, that's 
rather common with kernel development. It's probably a good idea to add 
1033732@bugs.debian.org to that list.

The instructions also contain this part:
"Avoid top-posting and favor interleaved quoting"
That's what I've been doing and is considered rather important, so try your 
best to do that too.

In your reply you should put the following things:

1) Your system worked find with kernel 6.1.15, but stopped booting after 
upgrading to 6.1.20 and resulted in a kernel panic
2) Copy the part between "----" from your initial report so that it shows the 
kernel panic, your motherboard info and the stack trace
3) Indicate that Bjørn identified ce7d894bed1a539a8d6cff42f6f78f9db0c9c26b from 
the linux-6.1.y branch as the likely culprit
4) After building a 6.1.20 kernel with just that commit reverted, your system 
booted normally again.
5) You reported that all to https://bugs.debian.org/1033732 and were asked to 
report the issue 'upstream' (which is what that mail is).

It could be that they'll ask you to test a patch. If it's just a simple/single 
patch you should be able to try that with the same procedure as you've already 
done, but replace the patch I provided with one they provide.
If you don't understand what they're asking or f.e. the kernel build is/seems 
too complicated, feel free to ask for help in (just) this bug.

Good luck and thanks in advance :-)
