This is a keyboard problem. The background is that the boot process
uses a different keyboard driver from the final kernel, and that it's
much more finicky than the kernel version. It seems to have got worse
in the last few years. I've found that a USB keyboard will do better,

The background for the *message* (not the apparent freeze) is that
your root file system can't be found. This happens typically when you
change the device name. For example, my situation is that I'm doing
development with a SATA disk drive and moving it from system to
system. On my machine the root file system shows up as /dev/ad4s1a;
on the other machine it's /dev/ad0s1a.
It's probably worth putting in a PR about this problem.
