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.
