I suspect this is a result of the following bug:

    13902 Fix for 13717 may break 8-disk raidz2
        https://www.illumos.org/issues/13902

As a result of that bug, which is not yet fixed, we have put a
workaround in place to stop the panics:

    13908 disable kernel FPU by default until it is stable
        https://www.illumos.org/issues/13908
        https://code.illumos.org/c/illumos-gate/+/1573

You'll want to make sure you upgrade your system so that it includes
this workaround.


Cheers.
