Hi Spec,
Yes. I've got Debian 11 installed on the A3000 as the main os,
and the A4000 changes between 3.1 and debian. The lastest working
kernel is 5.15, and I've been testing/reporting issues with the
latter ones 5.18/5.19
I have no idea about the debian numbering system, but I'm a little
surprised there's something that "seems" so recent for an 040..
Debian 11.x = bullseye, is the latest versions. The version for M68K is
called "bookworm/sid", the testing version.
Untill recently there was no support for m68K as the Architecture couldnt
keep up with all the changes. It's now what's called a "port", and not on
the official port. See 
https://www.debian.org/ports/
dude... I know at one stage the local Miga power users seemed to be
raiding mac accelerators and macs themselves for faster parts... :) Not
Seeking the CPU's! For example there are now adapter boards to make a
68060 cpu fit into a 68040 scoket. There is only minor differences
between the two cpu's.
