Hello! I've just encountered the bug too. I was receiving a snapshot while I was installing packages in a chroot running on a dataset. Both hung. I was running 20.10 from the live DVD (downloaded today) with the pre-installed ZFS version. I don't have access to the exact version numbers right now, because I'm running memtest (since this is a brand new laptop, thought might be bad RAM). When it's done, I'll check if the pool survived.
My other systems are running zfs-0.8.3-1ubuntu12.4 on a Kubuntu 20.04 and zfs-0.8.5-2~bpo10+1(/zfs-kmod-0.8.4-2~bpo10+1 - have to reload the module at some point) on a Debian Buster, which are fine for now. This is my first launchpad bug report, not sure whether I should post here, open a new bug or post it on OpenZFS github issues page. Please excuse me if posting here is wrong. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870559 Title: Kernel NULL pointer dereference while receiving zfs snapshots To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
