Dear Debian Team,

I am writing to report an issue with the built-in keyboard on a Microsoft Surface device while using Debian. The issue affects the install environment and the LUKS decryption password prompt. Here are the details of the problem:

---------------------------------------------------------------

Affected System:

- Device: Microsoft Surface
- Debian Version: Debian 12 "Bookworm"
- Package(s) Affected: Installation environment, LUKS decryption, possibly kernel or hardware compatibility

---------------------------------------------------------------

Issue Description:

During Installation:
The built-in keyboard does not work at all in the Debian installer environment. I had to rely on an external USB keyboard to navigate through the installation process.

Post Installation:
After installation, the built-in keyboard works in the GRUB menu, but it does not function when prompted to enter the LUKS decryption password.

After LUKS Decryption:
Once the system boots past the LUKS decryption stage, the built-in keyboard works as expected for typing the login username and password at the login screen.

External Keyboard:
An external USB keyboard works at all stages (installation, LUKS password prompt, and login).

---------------------------------------------------------------

Steps to Reproduce:

- Boot into the Debian installation environment on a Microsoft Surface device.
- Try to use the built-in keyboard (it does not respond).
- Complete the installation with an external keyboard.
- Reboot the system with LUKS encryption enabled.
- Observe that the built-in keyboard works in the GRUB menu but does not respond at the LUKS decryption prompt.
- After decrypting the system with an external keyboard, observe that the built-in keyboard works again at the login screen.

---------------------------------------------------------------

Expected Behavior:

The built-in keyboard should work during the installation process, at the LUKS decryption prompt, and throughout the entire system boot process without the need for an external keyboard.

---------------------------------------------------------------

Additional Notes:

- This issue appears to be related to the device-specific hardware (Microsoft Surface) and might be a driver or compatibility issue with the keyboard in the initramfs or kernel.
- I have tested this behavior with [mention any other versions or kernels, if applicable].
- If any further logs or information are needed, I would be happy to provide them.

---------------------------------------------------------------

I hope this information helps to identify the issue, and I look forward to any suggestions or fixes you can provide.

Thank you for your time and for all your hard work on Debian.

Best regards
