Take a look at my diagnosis here:
http://lkml.org/lkml/2010/4/26/335
It includes a rough-draft patch. I'd be very interested in hearing reports of
whether this fixes this smartctl issue in others' environments as it has in
mine.
The reason I haven't proposed it as a real patch is that there's probably a
better location for that code. Where I have it, it'll apply to every SCSI host
using the MPT Fusion framework, and if it's a hardware bug, perhaps we want it
to apply only to this specific LSI 1068 controller.
That said, I expect most requests hitting the device are already well-aligned,
so this wouldn't affect many requests even if it did apply to a
broader-than-necessary collection of hardware.
