Hi timo,

 Do you have plan to move the linux-firmware into jammy-security?

 Our customer met this issue when the unattended-upgrade upgraded the kernel 
from linux-oem-22.04d to linux-generic-hwe-22.04 (6.8.0-48), I did boot from 
the old oem kernel and upgraded linux-firmware by manual, then this issue is 
gone.
 So the linux-firmware should be upgraded with linux-generic-hwe-22.04 at the 
same time.

Bug description:
  [Impact]
  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.

  [Test Case]
  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.
