[Bug 2060727] Re: The keyboard does not work after latest kernel update

Hallo AaronMa (mapengyu),

In the first line of the file "/etc/apt/sources.list" file I can read:

# deb cdrom:[Xubuntu 22.04.3 LTS _Jammy Jellyfish_ - Release amd64
(20230807.1)]/ jammy main multiverse restricted universe

I follow the steps that you suggested.
I can tell you the good news, my keyboard is working again in kernel linux-image-6.5.0-1021-oem.

I notice during booting I get several error messages on the screen displayed, see attachted photo.
What is the source of these messages, BIOS or kernel, and could these be suppressed or solved so that they doesn't appear on the screen.

SRU Justification:
======================
[Impact]
Keyboard is lost after updated to 6.5.0-27 and oem-6.5-1019 kernel
versions.

[Fix]
Regression commit is found commit:
936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in translated mode")

Fixes:
9cf6e24c9fbf1 Input: atkbd - do not skip atkbd_deactivate() when
skipping ATKBD_CMD_GETID
683cd8259a9b8 Input: atkbd - skip ATKBD_CMD_SETLEDS when skipping
ATKBD_CMD_GETID

[Test]
Tested on hardware, keyboard works fine after bootup.

The regression commit is only in 6.5 stable, so SRU for 6.5 only.

[Where problems could occur]
It may break keyboard.
