sdc is an external USB drive, I'll try to unplug that.

I'll do but first I want to see a working terminal, too much stuff to debug otherwise.

It's grub2, non-UEFI. I don't normally reinstall it when I update the kernel, I only run 
grub-mkconfig. I did the same this time.

Good catch, although I'm not sure where to find that info in the available kernel log. 
I'll look better, I need to stop it from scrolling.

Good idea.

One of the last things printed in the kernel log is "random: crng init done". The random 
service is part (possibly the last service) of the boot runlevel which is entered after 
the sysinit runlevel. So apparently a lot of openrc stuff has already started 
successfully. Instead, nothing from the default runlevel is output. I'll re-check those 
services.
