Issue with Luks Not Decrypting Drives on Boot

Greetings Arch Community,

I'm reaching out because I'm experiencing a persistent problem with my Arch setup, which includes drive encryption. Until a few days ago, everything was running smoothly. However, now, after entering my encryption password during boot, LUKS is not decrypting my drives - specifically, root (/dev/sdb3) and home (/dev/sdc1). The system neither decrypts nor prompts for the password re-entry, regardless of how long I wait.

To troubleshoot the issue, I booted from a USB stick and managed to decrypt the drive with the following command:

sudo cryptsetup luksOpen {DriveName} crypt

I verified that all my files were intact. Additionally, to rule out any filesystem issues, I also ran a check using:

sudo btrfs check --repair {DriveName}

In addition to these steps, I've repeatedly ensured that I am entering the correct password, confirmed that all BIOS settings are as they were when the boot process functioned correctly, and verified that Grub is operating as expected—signified by my ability to choose which drive to boot from (I also have a Windows installation on a separate drive). Despite these checks, the initial problem of LUKS not decrypting my drives during boot persists.

Does anyone have any suggestions on how to solve this issue? I appreciate any help you can provide.

Thanks!

If it is you should not need to switch from a busybox based initrd to a systemd based one as both should work.

I am currently using systemd.

Have you tried reverting the last pacman upgrade?
