One thing: On 32bit, scrubbing a pool seemed to be much better at
triggering the kmem_alloc panics than various other I/O operations that
traditionally triggered it. If you're on such a system but got rid of
the panics, this might just be a matter of them re-appearing again.

The panics seem to lead to spontaneous reboots if X is running on the
machine (or that has been the seemingly deciding factor for me).
