Public bug reported:
I can't exactly give all the details that I want to here, as after
installing the kernel package from the devel/proposed repo, my system
became unusable... I had to reboot to 6.19, and I was no-longer able to
log in because many of the gnome config files in my home folder (and
other files I had written) were corrupted.
This is the kernel I was running.
Linux trinity 7.0.0-6-generic #6-Ubuntu SMP PREEMPT_DYNAMIC Mon Mar 9 17:53:15
UTC 2026 x86_64 GNU/Linux
From "linux-image-generic_7.0.0-6.6_amd64.deb"
$ lsb_release -rd
Description: Ubuntu Resolute Raccoon (development branch)
Release: 26.04
What I saw in "dmesg" after I got the system back up in 6.19 was
thousands of lines similar to:-
[ nnn ] BTRFS error (device nvme1n1p1): zlib decompression failed, error
-3 root 5 inode 119986601 offset 32948224
fstab looks like this (it's old, has not yet been switched to zstd)
/dev/disk/by-uuid/afa219b0-bd3b-4c1f-b1fb-79a2fc33d57c / btrfs
defaults,compress 0 1
Sorry for minimal info, but I wanted to get /some/ info out there so
hopefully others can avoid loosing data while testing.
