Cannot boot new system profile on librebooted x220 with luks

[Dariqq]

Hey everyone,

yesterday I updated my guix on a librebooted thinkpad x220 (libreboot 
version 20230625) with a luks encrypted drive and I can't boot into the 
new system profile. I get into the Guix Grub Menu and when I select the 
new profile everything gets locket up afterwards, i.e. the screen stays 
on the grub background and nothing ever gets loaded. (system commit is 
2b5c6e1a41e4ddcf4cfa53a319ed784a856eac5d)

My previous profile with kernel linux-libre@6.4.7 on commit 
8e8d20b6b35d3ab529f9045cc8a779cdcec9c471 still works fine.

I tried another drive without luks encryption and there everything works 
with the new kernel.

Any help is appreciated.
