Package: linux-image-6.0.0-0.deb11.2-cloud-amd64 Version: 6.0.3-1~bpo11+1 The bullseye-backports 6.0.3 kernel contains an ext4 bug that causes the filesystem to become corrupted after resizing the filesystem. See https://www.spinics.net/lists/linux-ext4/msg85795.html for details and a reproducer.
This is particularly problematic on systems that resize the root filesystem during boot using systemd-growfs or similar. ext4 remounts the filesystem read only after the checksum fails and the system becomes unbootable. This happens on the EC2 cloud images, for example. The fix at https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/fs/ext4?h=linux-6.0.y&id=2f8d9b94176d48d733a461e13bb4f6589653ba05 is in 6.0.8. Some further fixes are identified at https://www.spinics.net/lists/linux-ext4/msg86163.html but those haven't been merged yet. I haven't tested either, but I presume the fix already on 6.0.8 is enough and the remaining fixes are more for correctness. -- Dan Nicholson | Endless OS Foundation
