** Description changed: kernel get stucks at boot if console=ttyS* is specified in the kernel cmdline and that serial HW isn't available on the system. Reproduced with: 4.4 (from Xenial), 4.15 (from Bionic), 5.4 (native, Focal) and 5.7-next (mainline) Removing the non-existent 'console=ttyS*' parameter fixes the situation. I tested it using KVM/qemu, but it has been brought to my attention that it was reproducible in VMware as well. I think it is safe to say that it is unlikely to be specifics to a certain virtualization technology type. - Didn't test on baremetal, but I would suspect the same behaviour (until - I'm proving wrong). + Didn't test on baremetal yet.
