Colleague Dale Ghent, who's spent time both in ixgbe (he put X550 support into illumos and therefore OmniOS) and NVMe can speak more, but I don't think he'll disagree with anything I've said here.

    Has the issue with the Samsung drives been fixed? I haven’t tried it lately, but the 950 Pros were hanging. Those are 1.2a devices though, so I don’t know if that matters.

    Just worried that enabling 1.2 might result in crashy systems.
