I had a similar problem on IBM x3650 with 6 sata disks. While testing
zfs, I got kmem panic and after reboot same errors appeared.
OpenSolaris does not allow to boot from raidz and there can be only
one vdev in bootable pool, so I decided to make two pools if I need
raidz or multiple vdevs:
- one root pool (8G) (mirror disk0 disk1 ... disk5)
- one for data and other fs (raidz disk0 disk1 ... disk5)

    Everything should be made as simple as possible, but not simpler.
