Latest kernel aarch64 SD card image fails to boot from USB on Raspberry Pi 4

peat-psuwit commented 2 years ago

Describe the bug

The "nixos.sd_image_new_kernel.aarch64-linux" image from unstable channel fails to boot when flashed to a USB drive. The boot process hangs early in the boot process.

Steps To Reproduce

Steps to reproduce the behavior:

Flash this image to a USB drive. The tested build is build 156837727.
If using UART, update /boot/extlinux/extlinux.conf and change ttyS0 to ttyS1.
Plug this drive to a RPi 4 with updated EEPROM. Power it on.

Expected behavior

The image boots to the shell.

Screenshots

The boot process hangs with the following boot message, logged from UART:

RPi4HangBoot.txt

The boot proceeds from U-Boot to the kernel, but then hangs there.

Additional context

According to [1], it seems like in 5.14 the option CONFIG_RESET_RASPBERRYPI is demoted from y to m. The same email seems to suggest that the module (reset-raspberry.ko) is needed for USB to work. I checked the initrd of the image; the module isn't there. So, I guess if this module is included in the initrd, it could fix the problem. I'll try to create a PR to do that.

Notify maintainers

Assumes that nixos/modules/profiles/all-hardware.nix is how kernel modules is included in the SD card image: @samueldr Also tag SD card installer file for good measure: @petabyteboy
