[Bug 2084766] Re: Most Meteor Lake machines fail to boot into desktop after upgrading to the -48 kernel.

Hello Kevin, or anyone else affected,

Accepted linux-firmware into jammy-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/linux-
firmware/20220329.git681281e4-0ubuntu3.35 in a few hours, and then in
the -proposed repository.

Please help us by testing this new package. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed. Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

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.
