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
