Okay, that sounds like a good idea which I have not done before. I am
seeing how I can install Debian in an Qemu or VMWare setup to be able to
test that way.

I am not coming with excuses here, and certainly not childish ones at
that either. I am just pointing out that on my device the tests don't
run well because of memory shortage and my reasoning why I think it is
so.
I will as long as the system is as it is with these selftests, just run
single subtests at a time on target, but if I have new phy problems like
the one you have seen I have had before, then testing on target becomes
off limits.
