[SOLVED] ThinkPad P16s problems booting/decrypting after update

Hello!

I had an encrypted laptop in use for about a year.

I set it up with an encrypted container but now, after a normal update, and not using it for two days, am greeted with:

:: running hook [encrypt]
Waiting 10 seconds for device /dev/disk/by-uuid/{uuid-here}
:: running hooks [btrfs]
Waiting 10 seconds for device /dev/mapper/krypton ...
:: mounting '/dev/mapper/krypton' on real root
mount: /new_root: no valid filesystem type specified.
ERROR: Failed to mount '/dev/mapper/krypton' on real root
You are now being dropped into an emergency shell.
sh: can't access tty: job control turned off

Inside the emergency shell:

df -h

just shows 15.1G /dev and /run

uname -r
6.3.9-arch1-1

I also am seeing ACPI BIOS Error (bug): Could not resolve symbol AE_NOT_FOUND and a lot more...

I have the same setup running on my desktop from which I am writing to you

What now? Am I facing a hardware defect or did the last update just break my setup.
In any case, how should I proceed?
Any help appreciated!

Edit: Hm, I may be experiencing https://bugs.archlinux.org/task/77780 *sighs* There goes my Friday afternoon

Re: [SOLVED] ThinkPad P16s problems booting/decrypting after update

Now inside an install medium I did

cryptsetup luksOpen /dev/nvme0n1p2 luks

Entered my password and it was decrypted.
I then proceeded mounting it:

mount /dev/mapper/luks /old

Then I entered /old

Here I have:

ls -la

total 16
.
..
.snapshots
boot
btrfs
home
var
@
@home
@pkg
@snapshots

Entered @

cd /old/@

Checking /old/@/etc/fstab and /old/@/etc/crypttab

comparing the uuids from the fstab to output from `blkid`

Not sure what I should see...

blkid
/dev/mapper/luks: LABEL="ROOT" UUID="733...32e" UUID_SUB="5d...efe9" BLOCKS_SIZE="4096" TYPE="btrfs"

Looks the same as in /old/@/etc/fstab

Mounted /dev/nvme0n1p1 under /old-boot

Checked the entries of the /old-boot...

there is EFI folder, amd-ucode.img, initramfs-linux.img vmlinuz-linux and loader folder

inside /old-boot/loader there are my configs under entries/

Going there and checking the UUID...

Hm, it's the one from /dev/nvme0n1p2... should it be the one from /dev/mapper/krypton instead? It's worth a try (albeit a long shot)

Rebooting and .... same issue

Re: [SOLVED] ThinkPad P16s problems booting/decrypting after update

FIX in the end:

inside an install usb stick

# Decrypt container

cryptsetup luksOpen /dev/nvme0n1p2 luks

# Mount the container
mount -o subvol=@ /dev/mapper/luks /mnt

# Mount the /boot
mount /dev/nvme0n1p1 /mnt/boot

# Change root
arch-chroot /mnt

# Regenerate image
mkinitcpio -P

This time without any USB stuff attached

Because indeed I found some stuff in /mnt/var/log/pacman.log (or /old/@/var/log/pacman.log as previously mounted) like:

Just ran into the same problem with my P14s. Thank you for sharing your solution here, it also worked for me.

Re: [SOLVED] ThinkPad P16s problems booting/decrypting after update

Glad it helped!

Today I had the same problem on my desktop... no issues for many years. What a faulty usb device can do -.-

Stupid switch/usb-hub, it wasn't even a cheap one!
