Package: debian-cd Severity: Important The current Bullseye installer images don't include the "ast" video driver, making it impossible to install Debian on systems that don't have a fallback VGA BIOS (anything non-x86, e.g. ARM/OpenPOWER).
Ubuntu fixed this issue almost 5 years ago: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1514711 Please include the "ast" kernel module, which does not require any proprietary firmware to function, in the Debian installer CD images.
