Package: linux-image-arm64
Version: 5.14.9-2
Severity: important

Dear Maintainer,

In bullseye, version 5.10.70-1 has the CONFIG_EFI_GENERIC_STUB_INITRD_CMDLINE_LOADER
kernel configuration set to 'y'. In bookworm it is unset which disable this feature.

This kernel configuration parameter allows for the EFI stub of the kernel to
parse and use a 'initrd=' parameter to set up an initrd when booting from EFI.
Boot loaders like 'systemd-boot' or 'refind' set this parameter if configured
to pass an initrd. If the kernel configuration parameter is unset, the
`initrd=` paramater is ignored, and can result in an unbootable system because
the initrd has not setup the root filesystem.

Without the kernel configuaration set, it is not possible to use 'systemd-boot'
or 'refind' on arm64 as both of these bootloaders assume the kernel will
handle the 'initrd=' flag and setup the initrd.

Please consider enabling CONFIG_EFI_GENERIC_STUB_INITRD_CMDLINE_LOADER on
arm64 so using 'systemd-boot' or 'refind' can continue to work. Until these
bootloaders have been updated to use an alternative method of passing the
initrd to the EFI stub, it is not possible to have a booting system.
