Control: reassign -1 raspi-firmware 1.20210111+ds-2 Booting linux kernel 5.10.x from USB MSD needs either * loading reset-raspberrypi.ko in initramfs, * or rebuild kernel with CONFIG_RESET_RASPBERRYPI=y in .config
Anyway, the combination of linux-image-arm64/sid and raspi-firmware/sid does not allow booting RPi4 from USB-MSD. Boot from USB-MSD was possible in Debian kernel 5.9 series. I think this boot failure should be fixed by echo reset-raspberrypi >/usr/share/initramfs-tools/modules.d/raspi-firmware.conf instead of CONFIG_RESET_RASPBERRYPI=y. If this is considered an issue in src:linux, please reassign this back. Best regards, Ryutaroh Matsumoto
