Bug#1083262: Bug Report - Built-in Keyboard Issue on Microsoft Surface in Install Environment and LUKS Decryption

[scored_mounting044@simplelogin.com]

Package: linux-image-amd64 (or initramfs-tools)

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:

1. 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.

2. 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.

3. 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.

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

---

Steps to Reproduce:

1. Boot into the Debian installation environment on a Microsoft Surface device.
2. Try to use the built-in keyboard (it does not respond).
3. Complete the installation with an external keyboard.
4. Reboot the system with LUKS encryption enabled.
5. Observe that the built-in keyboard works in the GRUB menu but does not respond at the LUKS decryption prompt.
6. 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
