Then I'd have to figure out how to get a new kernel into it while it
crashes during bootup,
which it now does quite consistently.

If I had made recent changes (such as upgrades) I'd consider a kernel
problem more likely.
But it has been running for months with only occasional problems, and now I
get problems
every time I boot. Since I haven't done an upgrade at all yet this month,
I'll suspect hardware.

Still, I will try, say, a chimaera live CD if I can find one. Where are
the Devuan live CD's?
I seem to remember that they were called something other than "devuan".
(Yes, I'm aware that the live CD will likely be a USB stick)
