I think this may be a race condition, in which case duplicating this issue and testing a fix may be problematic.
I've created a potential fix and tested this against our internal regression tests, so it may be worth tying this to see if the issue occurs with the fix. To try this out do the following: sudo add-apt-repository ppa:colin-king/zfs-src-1900889 sudo apt-get update sudo apt-get upgrade sudo apt-get install zfs-dkms This will pull in the fixed version including the kernel ZFS driver - the DKMS ZFS driver may take several minutes to build. Once done, a reboot is required. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1900889 Title: BUG: kernel NULL pointer dereference, address: 0000000000000000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1900889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
