I am rather sure this one is a variation of bug #1814555 for which an
update should be available soon. Marking as duplicate now but if the
4.18.0-15.16 does not help, you can revert that.

Title:
kernel hangs on boot after "fb: switching to inteldrmfb from VESA VGA"
Status in linux package in Ubuntu:
Confirmed
Bug description:
A few days ago, I let update-manager upgrade my kernel from 4.18.0-13
to 4.18.0-14. Since then, my system is unable to boot. It freezes
after printing
fb: switching to inteldrmfb from VESA VGA
but before it gets around to asking me the passphrase for my encrypted
main partition. (At first I thought it was a problem with cryptsetup
because it never got to that prompt, but now I'm pretty sure it's
something to do with changing video mode.)
However, if I use the grub menu to select the older 4.18.0-13, the
system boots just fine. It looks very much like a bug introduced
between 4.18.0-13 and 4.18.0-14.
Additionally, if I boot 4.18.0-14 in maintenance mode, the kernel
modesetting does not happen, and the system boots just fine. (Except
for the 1980s-style low-res video, that is.) This seems like good
evidence that it's a problem with setting the video mode.
I'll test with some mainline builds, but I want to get this bug report opened
before I start rebooting.
