Last update broke my cryptsetup and causes kernel panic on boot

I did a system update this morning and rebooted, and can't login anymore.

On boot, cryptsetup won’t let me enter my password (every keystroke acts like the return key, resulting in the “no key found for this passphrase” message), and then a wild kernel panic appears.

I don't know yet if this problem is unique to my setup or others can be affected too, but just in case I created this thread as a warning.

I'm not at home right now for further details and analysis, I'll try to see what I can do with a live system later on.

Re: Last update broke my cryptsetup and causes kernel panic on boot

Hi!

I had a possibly related issue today after updating some packages, although I never got a kernel panic.

After a rebooting, I was able to unlock my dm-crypt partition containing an LVM volume with my root partition with my normal password but the boot process was *not* able to automatically unlock /home or unlock it using a manually typed password. Instead, I got an "error creating IV" and several device-mapper errors. However, I could still log in as root. Doing cryptsetup luksOpen for /home resulted in the same error. I also noted a FAT32 error message in dmesg about my efi partition.

The solution for me was to downgrade systemd packages from versions 226-3 to versions 225-1. Then the OS could boot normally without these errors.

Kernel Panic is gone, but I still can't enter any passphrase, same behavior as in OP. Quite annoying.

Is this a USB keyboard?

I am asking because perhaps something went wrong when making the initramfs image and the necessary keyboard related modules are not present or broken.

Btw, does the keyboard work, for instance in the BIOS? Do you have a different keyboard that you could try?

Same behavior both with the USB keyboard (which works in BIOS) and with the notebook's built-in keyboard; no difference either if I plug or unplug the USB keyboard.

Re: Last update broke my cryptsetup and causes kernel panic on boot

I know you are not trying to auto-mount, so this may have nothing to do with your problem, but I did run into a cryptsetup / systemd issue that I think was related to the user-sessions changes in systemd. See https://bbs.archlinux.org/viewtopic.php?id=202807. Could have nothing to do with your particular problem.
