The first is a fix for the second so these should be tested together.
None appear suspect to me.
Running memtest could incur a boot delay but AFAIR that isn't enabled by
default, and it isn't implicated in the panic log Adrian posted.
I don't have time this weekend to bisect the issue. But I think, I can start
bisecting it on Sunday evening. I will give it a try on Amiga Forever.
I had hoped we could maybe narrow down the range to bisect by compile...
As it stands, testing each Debian kernel image released since 5.15.2
already requires a bisect approach so you indeed have your work cut out
for you.
Let me know what you find - the list of commits in mm/ is too huge to
contemplate in its entirety but might be easier to digest from one
release to another.
Cheers,
