** Description changed: - After installation the display only turns on after the initramfs. This - means there is no visible input field if disk encryption was selected in - the installer. + [ Impact ] - The initrd seems to be missing the panel module. + On affected hardware, the display only works after the initramfs. + This means there is no visible input field if disk encryption was selected in the installer. + The same of course applies for any other output during the initramfs. + + [ Test Plan ] + + To reproduce the issue, install an affected machine with disk encryption or add break= to the kernel command line to get an interactive initramfs shell. + With the bug present the screen stays dark. It might still be possible to enter + the passphrase blindly or exit the debug shell. After modules are loaded from the root file system the screen should start working. + + With the patch applied there should be visible output for the password + or shell prompt in the initramfs. + + [ Where problems could occur ] + + The fix should only include additional modules, we should make sure not + to accidentally drop any functionality in the process. + + [ Other Info ] + + Since dracut and initramfs-tools behave similar enough the same test + plan should apply to both. Both are already fixed in questing and there + is positive test feedback from users in discourse + https://discourse.ubuntu.com/t/faq-ubuntu-25-04-on-snapdragon-x- + elite/61016/18
