This is a bug in the ZFS kernel code which should be reported upstream.
The ZFS module contains code that produces unaligned access and the kernel
fixes that. It's not a problem per se because the kernel can work around
that. But it should probably get fixed.

This just means that your CPU doesn't support this particular instruction,
this is merely an information and not an indicator of a problem.
