Bug description:
[Summary]
During the SRU testing, I found many laptops displayed a black screen after booting. Those machines are still alive and able to access via ssh, just nothing displayed on the screen.

After a brief check, those affected machines that I inspected are all
Meteor Lake machine.

I just attached the journal.log from one of the affected machines.

[Reproduce steps]
1. restore the system the initial state.
2. run dist-upgrade
3. enable proposed pocket.
4. apt install linux-generic-hwe-22.04
5. reboot

[Fail rate]
5/5

[Expected result]

Machines can boot into desktop environment.

[Actual result]

Nothing display.
