Getting QR code on boot - Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

General system Kernel, boot, graphics & hardware
1

The new rust based kernel crash stuff is awesome… I just wish I didn’t have to use it :P.

Background

My workflow is usually something like this:

  • Reach a good point to close everything, run updates, reboot
  • Use computer, sleep/wake a few times per day for ~ 2 weeks
  • (repeat).

I am currently booted via an older snapshot:

[root@hedt boot]# uname -a
Linux hedt 6.14.3-arch1-1 #1 SMP PREEMPT_DYNAMIC Sun, 20 Apr 2025 12:38:52 +0000 x86_64 GNU/Linux

What’s happened

After a recent yay run, I rebooted to find out that I was unable to boot. I enter my luks password and grub menu shows up. After the usual timeout, the default entry boots and almost immediately renders the new blue screen w/ QR code.

The full boot log from the QR code is here, but the critical bit is this:

I am on a fairly new (about 2 months old) EOS install. I chose the standard btrft + encryption option from the graphical installer.

Fortunately, I have grub-btrfs snapshots; I was able to go back to an earlier snapshot to boot and post this message asking for help.

Some other details / possibly related symptoms

Recent snapshots are detected by grub-mkconfig but don’t show up on the boot menu!?

While doing initial troubleshooting, I noticed a few things that … are probably related, but I’m not 100% sure how.

  • I can run grub-mkconfig which triggers the btrft snapshot hook. The console output includes very recent snapshots… BUT they do not show up on the grub boot menu.

Output:

Notice the 5+ snapshots with 2025-04-20 in the date? Yeah, the most recent snapshot to show up on the grub boot menu is 2025-04-19.

Of the detected snapshots that do show up on grub menu, some don’t even load the kernel.

As shown above, I have some snapshots that are recent (today, 2025.04.20) but they do not show up on the grub menu! But ok, let’s try to boot off of the most recent snapshot that does show up!

when I try that I get this error:

Loading Snapshot: 2025-04-18 20:00:00 timeshift-btrfs/snapshots/2025-04-18_20-00-0

Loading Kernel: vmlinuz-linux ...

Loading Microcode & Initramfs: amd-ucode.img initramfs-linux.img

error: you need to load the kernel first.

Press any key to continue....

I am currently booted off of a snapshot dated from the 17th…

Hmm…a few things.

  • If you use timeshift, be exceptionally careful you never run grub-mkconfig or update your system when booted off a snapshot, this will cause a big mess that is a bit painful to unravel.
  • Be sure sure your pre-hooks are running in the right order. There is a pre-hook that deletes the kernels/initrds. Be sure this runs after the pre-hook that takes your snapshot.
  • I can’t really tell from that error message if it failed to unlock your luks volume or if you are missing the btrfs modules.

… that is good to know even if the timing’s not ideal.

Exactly how big of a mess to unravel are we talking about, here?
(I have run yay and -mkconfig since booting from a snapshot…)

4

Presumably the latter? I need to provide a password to unlock before even grub menu shows up…

5

Take a look at your grub.cfg, you are probably permanently booting off a snapshot.

Also, if you have done this in the past, it is possible that you have been taking snapshots of a different subvol than the one you were booting.

6

It actually gets unlocked twice when you use grub. Grub unlocks it and then the initram unlocks it again.

7

Is the password / derived key kept in memory or is the first password just enough to unlock grub and a key file?

8

The password is used to unlock grub and then the initram uses a keyfile to unlock it the second time.

I think you’re right…

is it really a simple as:

sudo mv /boot/grub/grub.conf /boot/grub/grub.conf.ORIG
# This is the newest snapshot
sudo cp /run/timeshift/27429/backup/timeshift-btrfs/snapshots/2025-04-20_12-07-27/@/boot/grub/grub.cfg /boot/grub/grub.conf

sudo cp /run/timeshift/27429/backup/timeshift-btrfs/snapshots/2025-04-20_12-07-27/@/boot/grub/grub-btrfs.cfg /boot/grub/grub-btrfs.conf

Or am I missing something?

10

Probably not. If you try to copy an old one, it might not be in sync with the files in the current snapshot.

11

So the path of least pain is to backup + reinstall?

12

If you caused this issue because your system wasn’t booting, then yes, that is probably the best. Because, even if it we fix it, it will just put you back to a situation where your system wasn’t booting.

However, if the system is not booting because you booted into the snapshot and ran operations, then you can fix it by manually editing grub.cfg or booting off the ISO and chrooting in.
