I've debugged this back down the stack and there is a null pointer that should be caught by some assert checks but strangely isn't being reported, so a null pointer crash in the abd_verify function is most unexpected.
I've build a zfs debug package that contains more information of internal pointer state that may help debug this further at: https://launchpad.net/~colin-king/+archive/ubuntu/zfs-sru-1870559 sudo add-apt-repository ppa:colin-king/zfs-sru-1870559 sudo apt-get update sudo apt-get install zfs-dkms and then reboot When you get another crash hopefully there will be more data captured in the kernel log -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
