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.
