New uboot doesn't know btrfs #517

Closed DrRac27 closed 1 year ago

DrRac27 commented 1 year ago

Steps to reproduce

I have been using the same install of arch for a long time. I used FDE + btrfs to install it and until now everything worked but now i compiled the new kernel and the new u-boot (uboot-pinephone-2023.01-1-aarch64.pkg.tar.xz), made a full update and now it boots into an emergency shell with the error message: mount: /new_root: unknown filesystem type 'btrfs'. Did you disable btrfs in the u-boot config? (I checked kernel & u-boot -> you didn't. The commits shouldn't have anything to do with btrfs....)

Expected behavior

Boot as every time before.

Actual behavior

Boots into emergency shell. Doesn't open a osk so I can't type and find out more because I have a unpatched UBPorts Edition where the USB data pins have to be soldered somehow (didn't look into it yet).

Logfiles and additional information

FDE unlocking works.

The btrfs module is not built in, but rather as a module.

Try boot to another Linux install, mount root to /mnt and boot to /mnt/boot. Chroot in, add 'btrfs' into list of modules in /etc/mkinitcpio.conf and regenerate initramfs.

This is nothing that changed so I didn't think it could cause the problem. And in fact all that was necessary was to regenerate the initramfs. Maybe my -Syu failed? It is working again. I am a bit confused because I checked my /etc/mkinitcpio.conf and the modules array is empty and it works anyways?
