Public bug reported:
ZPool was functioning before upgrading to Ubuntu 18.04. Unfortunately
didn't confirm pool working before upgrading the pool so can't roll
back. Can't access file system anymore, though a scrub did succeed.
Simple 'ls -la' segfaults, and this shows up in dmesg:

Title:
File System inaccessible after 18.04 upgrade
Status in zfs-linux package in Ubuntu:
New
Bug description:
ZPool was functioning before upgrading to Ubuntu 18.04. Unfortunately
didn't confirm pool working before upgrading the pool so can't roll
back. Can't access file system anymore, though a scrub did succeed.
Simple 'ls -la' segfaults, and this shows up in dmesg:
