I'm currently not running the affected kernel version, since the system is being used as a backup-target (hence the high subvolume count), therefore I cannot provide the requested log. My initial bug report contains the information that should help determining which commit is missing from the kernel. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901755 Title: "btrfs subvolume list" sporadically segfaults with linux- image-5.4.0-52-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1901755/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
