Public bug reported: This hangs Linux warm/cold boot for all versions with non-uniformed fail rate. With v5.2 or older, it's almost 100% reproducible; with v5.3 or above, it's much less likely. With kernel boot parameters `initcall_debug ignore_loglevel=1 earlyprintk=efi earlycon=efifb`, it shows it's mostly locked up inside lock access in `console_init()`, but it may also sometimes happen when early console is not even initialized. On Ubuntu Bionic, the first known failing version of intel-microcode package is 3.20191115.1ubuntu0.18.04.1. By reverting this package to any prior revision and such hard lockup is then gone. Another possible temporary work-around is to disable SMP by passing "nosmp" to kernel.
This is currently reproducible on Intel i5-8365U, model 142, stepping 12.
