I did not run it this way, will do.
I had it however, of a very big size:
316M Jan 14 17:15 initrd.img-5.9.0-rc1+
which filled up my /boot
I removed it, regenerated with your command, but I get dropped into
initramfs with no modules found. Hmm..

Not nice. I started compiling some stuff and the box froze, I connected
serial console and could not resume due to Fast Data Access MMU miss"
I will now stress things again, but keeping serial console attached with
another computer and see.
UP to last week with the old 5.9 kernel I had no issues compiling even
large things as gecko based ArcticFox or the Linux kernel itself. So if
the Fire didn't fail over the weekend.... it smells as kernel instability.
What should I use in stress-ng? I just tried "--all 8 --timeout 120s"
and the machine locked up after a little and in the serial console I see:

These are kernel messages, not OF, so it looks like a kernel problem
