It happened to me too and I'd like to receive notifications on this bug (I didn't figure out another way besides leaving a comment).

Hello, I used
"qemu-img create -f raw example.img 200M"
to created a 200Mb image file, and
"losetup /dev/loop0 example.img",
mounting example.img as a loop device.

Then I formatted the /dev/loop0 by mkfs.btrfs with default options,

"mount /dev/loop0 /boot",
mounting the loop0 device to /boot,
copied the amd-ucode.img file to /boot/amd-ucode_src.img, and I noticed that I had enabled the zstd compression for my root partition, so I ran
"btrfs filesystem defragment -r -v -czstd /boot/"
to compress the amd-ucode_src.img file.

After that, started the beesd service for loop0, install the amd-ucode package by package manager, then I confirmed  the bees deduplicated the amd-ucode.img.

umount the /boot and "losetup -d /dev/loop0",
I compressed the example.img file with zstd.
I am not sure this image could cause the grub boot failed, just control the variables as same as possible.
Thanks!

> Can you recreate this with a small image and send it to me? You can use grub-fstest IMAGE cmp PATHINIMAGE PATHEXTERNAL to check if GRUB sees your files correctly


When I try to create a 16Mb raw img file and mkfs.btrfs the image file I got a massage:

> mkfs.btrfs example.img

btrfs-progs v6.3.2
See https://btrfs.readthedocs.io for more information.

ERROR: 'example.img' is too small to make a usable filesystem
ERROR: minimum size for each btrfs device is 114294784

I need to find some ways to upload the file above 16Mb

or i just uploade it to cloud storage.

I updated amd-ucode package from a old version A to the new version B, then reboot system, I got following error during grub loading microcode:

> error: start_image() returned 0x8000000000000001


changed the line 
"initrd  /boot/amd-ucode.img /boot/initramfs-linux.img"
to
"initrd /boot/initramfs-linux.img"
in /boot/grub/grub.cfg, the system booted.

I just downgraded amd-ucode back to version A, but the system boot was still failed.

After multiple attempts, I found that boot failed is not associated with amd-ucode, I had enabled beesd service for deduplicating root partition nvme1n1p5, and bees just deduplicated the /boot/amd-ucode.img, which caused the failed.

Disabled & stopped beesd, reinstall amd-ucode with any version, system boot successfully.

There might be something wrong with grub btrfs model.

Maybe this procedure can reproduce the issue:

1. enable & start a beesd service for root partition;
2. pre-save the amd-ucode.img to somewhere in root partition;
3. install the amd-ucode package, that the package manager install the same amd-ucode.img file to /boot/, and triggering bees deduplicate /boot/amd-ucode.img
4. reboot, grub fail in boot.


these are output of "btrfs inspect-internal dump-tree " about amd-ucode.img file with and without beesd enabled:
