I've uploaded a potential fix to a PPA, do you mind testing this using the zfs-dkms kernel modules as follows:
sudo add-apt-repository ppa:colin-king/zfs-sru-1861235 sudo apt-get update sudo apt-get install zfs-dkms and reboot. Then check the correct ZFS module is being used by: dmesg | grep ZFS It should be the 0.7.5-1ubuntu16.9~lp1861235 version. And see if this helps avoid this issue. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Also affects: zfs-linux (Ubuntu) Importance: Undecided Status: New ** Changed in: zfs-linux (Ubuntu) Status: New => Incomplete ** Changed in: zfs-linux (Ubuntu) Importance: Undecided => High ** Changed in: zfs-linux (Ubuntu) Assignee: (unassigned) => Colin Ian King (colin-king) ** Also affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: zfs-linux (Ubuntu Bionic) Importance: Undecided Status: New ** No longer affects: linux (Ubuntu) ** No longer affects: linux (Ubuntu Bionic) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861235 Title: zfs recv PANIC at range_tree.c:304:range_tree_find_impl() To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1861235/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
