see it every boot ?
I don't look every boot. The warning gets scrolled of the screen. Once I see
the CPU hang warnings I know the boot is failing. I don't always look
at journalctl later to see what's there.
I'm going to revert a0747a859ef6 for now, since we're now 8 days into this
and no progress has been made on fixing it.
One important thing I have just found is that it looks like the problem
only happens when booting in enforcing mode. If I boot in permissive
mode it does not happen. My home machines are currently set to boot in
permissive mode and I'll test this evening to see if I can reproduce the
problem if I change them to enforcing mode. If so I'll be able to do lots
of testing during my vacation.
