Although this is closed as dup, I thought would be good to clarify why
Debian Buster doesn't reproduce (at first). What happens is that Debian
includes the fsck on initrd by default, and in Ubuntu that doesn't
happen - the reason behind it is that rootfs is marked as always-verify
in the 6th field of fstab (fs_passno) in the Debian cloud image I got,
whereas Ubuntu cloud image use the default value, 0.
Once I changed Debian to not include fsck on initrd, it reproduced the
issue. And once I set Ubuntu rootfs to have value 1 on fstab's 6th
field, it stopped to reproduce. When fsck is on initrd, we don't
log_warn "fsck not present, so skipping $NAME file system", so we don't
fail in _checkfs_once(), hence there's no infinite loop on checkfs().
Cheers,
Guilherme

Title:
machine get stuck at boot if specified 'console=ttyS* ' doesn't exist.
Status in initramfs-tools package in Ubuntu:
Confirmed
Status in linux package in Ubuntu:
Incomplete
Bug description:
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 yet.
