I wasn't able to panic my test machine running this command on i386
machine with this in /boot/loader.conf:

vm.kmem_size=1073741824
vm.kmem_size_max=1073741824

(1GB)

Although I now found that you were trying raidz2 and I had two two-way
mirrors. I'm retrying now.

PS. The panic is not yet fixed completely, unfortunately, but it should
be a bit harder to trigger it now.
