--- Comment #23 from Hannes Reinecke <hare@xxxxxxx> ---
So the firmware does indeed wedge under high load. Given the issues I've had so
far with LSI SATL I'm not surprised.

Does the same thing happen when running on a single disk, ie without MD?
There have been issues with MD dropping any queue limitations (ie the 4k
physical / 512 logical block sizes you're having) so MD might end up spitting
out non-aligned requests. Which in turn might trigger issues in the firmware
translation.

Using the devices directly without MD would eliminate this problem.
