@marcin-github My suspicion is your user space utilities are out of sync with the loaded ZoL kernel modules. In particularly, it appears the new kernel modules with the new feature we not loaded on your system. Now that shouldn't cause the utilities to core dump but still I suspect that's your issue. I'd rebuild everything and make sure the old modules get unloaded.

[marcin-github]

You are completly right Brian. I was planning to unload/load modules but I have to did something else, next I was sure I have new modules loaded.

[behlendorf]

Great, then I'm going to close this issue.
