nokia-n900: FDE broken

Describe your issue

What's the expected behaviour?

FDE image should boot to desktop

What's the current behaviour?

Image boots, and unl0kr screen comes up. However:

1. Touch does not work at all, so the unlock screen cannot be interacted with
2. After unlocking using the integrated hardware keyboard, the following error shows up on the console log, and after a while, the unlock screen comes up again, and the cycle goes on indefinitely:

device-mapper: table: 252:0 crypt: Error allocating crypto tfm (-ENOENT)
device-mapper: ioctl: error adding target to table
device-mapper: reload ioctl on root (252:0) failed: No such file or directory

How to reproduce your issue?

On what postmarketOS version did you encounter the issue?

• edge (master branch)

• v24.06

• v24.12

• I confirm that the issue still is present after running sudo apk upgrade -a *(No idea since boot does not reach a point where that can be run)*

On what environment did you encounter the issue?

Environments

• GNOME Shell on Mobile
• Phosh
• Plasma Mobile
• Sxmo (Wayland/Sway) Please post the output of sxmo_version.sh
• Other: i3wm *(issue should be UI-independent)*

How did you get postmarketOS image?

• from https://images.postmarketos.org
• I built it using pmbootstrap
• It was preinstalled on my device

What's the build date of the image? (in yyyy-mm-dd format)

N/A since image built via pmbootstrap

Additional information

From researching online, I found a similar Ubuntu/Debian bug which suggests the issue is related to compressed kernel modules not being included in the initramfs.

However, this seems not the cause here, since unpacking the initramfs shows all modules are in place:

initramfs file listing: initramfs_listing.txt

I would like to get some pointers to resolve the issue in time for v24.12
