I spoke too soon.
The problem of the SATA 3 drive being FAULTED in the raidz2 pool has indeed
been solved by moving that drive from the Super micro (SAS 6G) controller
to the onboard Intel (SATA 2) controller.

However, the 157k interrupts per second problem remained (its not apparent
immediately after boot).

However, even this problem has been resolved by upgrading from 8-STABLE to
9-STABLE (as I reported in the freebsd-stable list).

So I'm happy now but still no closer to understanding the cause.

I'm guessing that it was either USB related or something to do with the on
CPU package Intel graphics of the Core i3 530 CPU.
