Bug#1027458: MODULES=dep unbootable on Raspberry Pi 4 booting from USB
Package: initramfs-tools
Version: 0.142
Severity: important
Dear Maintainer,
If MODULES=dep is used to trim generated initramfs on Raspberry Pi 4, it results in unbootable initramfs generated if user boots from USB-connected external drive (rather than microSD).
In particular, system is unable to find rootfs and after a brief delay bails out to shell prompt.
In order to make it work, reset_raspberrypi module has to be included. This is the case with MODULES=most, and precise reason why only MODULES=dep is affected. For MODULES=dep scenarios, reset_raspberrypi has to be manually added to /etc/initramfs-tools/modules.
I'd like to request a bugfix in this regard to always include reset_raspberrypi module in generated initramfs if it's loaded at the time of generation or it's otherwise determined that initramfs is generated for a machine is Raspberry Pi 4.
If it helps, reset_raspberrypi module is loaded anyway during later stage of the boot process, so it doesn't hurt to load it earlier right in the initramfs even for setups that would work correctly with it being loaded later on.
I'm not familiar with all internals of how initramfs-tools works, so I apologize in advance if I mixed something up. This is also I think my first or second bug report ever done, so please bear with me.
Thank you in advance for considering this enhancement/bugfix,
Archi.
