does every time boot fail can trigger WANRING in device_add_disk ?
Not that I see. But the message could scroll off the screen. The boot gets
far enough that systemd copies over dmesg output to permanent storage that
I can see on my next successful boot. That's where I looked for the warning
output you want. I never saw it for any kernels I compiled myself. Only
when I test kernels built by Fedora do I see it.
I just tried booting to single user and the boot still hangs.
When I build the kernels, the compiler options are probably a bit different
than when Fedora does. That might affect what happens during boot.
