The problem with this controller is that if you try to use smartctl or
smartd to monitor your drives, the controller will become unresponsive
and offline an arbitrary amount of drives. This causes a huge problem
in raid because then the drives get marked as failed and I have to
force add them back into the array.

This is a known issue with the 1068 series which AFAIK there are some
patches floating around that resolve this issue. Refer to
https://bugzilla.kernel.org/show_bug.cgi?id=14831 for particulars.
