Public bug reported:
On kinetic pi server daily images with the 5.19 linux-raspi kernel (e.g.
from http://cdimage.ubuntu.com/ubuntu-server/daily-
preinstalled/current/) there is no console output over HDMI. The
"rainbow" boot screen appears as usual, but then remains while the
system continues to boot and never switches to display the console.
The system does still boot successfully, I can SSH into it, and console
over serial still works but not over HDMI (testing on a Pi 3, and two
revisions of the Pi 4). Adding either kms overlay (vc4-fkms-v3d or
vc4-kms-v3d) to the boot configuration resolves this. Is it simply the
case that future kernels are going to require a KMS overlay of some
flavour or other to operate the console?
If so, that's probably a good thing to some degree (it'll remove another
difference between the pi server and desktop images), but ubuntu-
release-upgrader will need to work to enforce that in the boot
configuration for upgraders (and I'll need to tweak the gadget to ensure
it's always included from now on).
