[SOLVED]ZFS and disk by-uuid naming after upgrade to linux-4.6.1-2

After upgrading to linux-4.6.1-2 'zpool status' gives me:

  pool: dysk1
 state: ONLINE
  scan: scrub repaired 0 in 4h7m with 0 errors on Sun Jun  5 08:07:51 2016
Cancelled

and dumps core:

                Stack trace of thread 6389:

zpool status -g works:

something is wrong with disk naming.

lsblk -f output:

Why I cannot see UUID for all disks?  What can be done about it?

Re: [SOLVED]ZFS and disk by-uuid naming after upgrade to linux-4.6.1-2

Solved.
I disabled ZFS autostart:

systemctl disable zfs.target

did a reboot, and then imported my pools:

zpool import <pool>

then enabled ZFS autostart and after another reboot "zpool status" works.
