I was NOT able to boot with mitigations=off now. If you review the line

> BOOT_IMAGE=/vmlinuz-5.0.0-15-generic ... dis_ucode_ldr mitigations=off

I made a mistake, microcode disable was still there. So backtrack one level, mitigations=off have no effect, do not help. I still need the dis_ucode_ldr
Once again, sorry for that. I was thinking I'm going crazy when I couldn't boot with mitigations off now, so I'm actually happy it was the mistake between the chair and keyboard.

Back to

for any logical CPU:

# cat /sys/devices/system/cpu/cpu*/microcode/version
cat: '/sys/devices/system/cpu/cpu*/microcode/version': No such file or directory

but that is I'm only able to boot if ucode is disabled.

I'll now try the non-ubuntu kernel and post the same.
