    When new provider is created it is given for taste to other classes.
    This interrupt storm could be a result of some kind of abuse from
    one of existing classes.

    Could you provide output of command:

            # sysctl -b kern.geom.conftxt | awk '{print $2}' | sort | uniq

    It will be good if you could try unload some classes (gvinum, etc.) before
    loading geom_stripe, just to be sure.

    Increasing kern.geom.stripe.debug could be also interesting.
