Not solved with kernel 6.11.3 having the exact same issue. Checking the kernel updates about f2fs it seems that there is some rework for zoned devices, which includes "discard" or "trim" operations. Any idea if any of those could be the culprit? Thanks, pg I tried to investigate a bit this item. On a different PC, I could not reproduce the problem. On this PC, I notice the issue occurred immediately when creating the snapshot, not when removing it. This PC has 3 LV: root (32GiB) home (480GiB) data (256GiB) The one causing the problem was "home". So I tried the other two, and everything was working fine, no issue. The only difference I could see is the size. After, I re-tried "home", and, surprise, no problem also there. It seems something fishy is happening. From one side, it's good the problem is gone, from the other... It's not solved.. Hope this helps, pg One more update. After reboot, problem again there. And again reboot, if I snapshot another LV, I can, after, snapshot "home" without problems. If I snapshot "home" first, then there is the NULL pointer de-referencing error. Not sure what to do with this, but I would be nice if someone could provide some hints... Thanks, pg Hi all, kernel-6.12.4-100.fc40.x86_64.rpm (from Koji build) seems to carry the patch for this problem. Some testing resulted in no issues anymore. I think you can close the bug. Thanks! Merry Christmas & Happy New Year! bye, pg I think this was fixed and can be closed. Thanks! This message is a reminder that Fedora Linux 40 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 40 on 2025-05-13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '40'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 40 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed. Hi all, as already reported, this was fixed. Can be closed (even if it will automatically). Fedora Linux 40 entered end-of-life (EOL) status on 2025-05-13.
