OS-X-SAT-SMART-Driver + OpenZFS on OS X 1.4.5 renders system totally unreliable/unstable #40

System: Mac mini (Late 2012) OS X: 10.11.3 OS-X-SAT-SMART-Driver: 0.8 OpenZFS on OS X: 1.4.5 USB 3.0 Drives: 6x Seagate STDR2000200, 2x Seagate STDT8000200

Running the system with one of both drivers (OpenZFS or SAT) without any issues.

Having both drivers installed, the system becomes totally unreliable and constantly crashes (and auto-restarts) during disk I/O. The ZFS pool is configured as striped RAIDZ (6 disks) and a mirror (2 disks), but I doubt that this is relevant.

If the system stays up and a data transfer involving the ZFS pool is started, it stalls after random number of bytes but 36 GB at maximum.

As said before: using OpenZFS or SAT exclusively, everything is fine.
