Title:
Cannot enter luks password at boot after kernel 6.8.0-50 upgrade

Status in linux package in Ubuntu:
Confirmed

Bug description:
Upgraded Ubuntu 24.04 software, including kernel 6.8.0-50, after which
upon booting the luks password couldn't be entered (dialog
unresponsive). Was able to boot 6.8.0-49. Could boot 6.8.0-50 with
quiet splash commented out - with text input.

Added i915 (my video driver) to /etc/initramfs-tools/modules and
updated initrd, after which could boot 6.8.0-50.
