I reverted to that revision but the problem was still apparent. So I've now tried: - Previous BIOS - Updating the controller firmware from phase 7 to phase 11 - Going back to the old (pre LSI authored) mps driver But all to no avail. What has worked is to move the single SATA 3 (6 Gbps) drive (the other 7 drives are SATA 2) to the onboard SATA 2 Intel controller. So it seems that both the old and new mps driver have a problem with the Western Digital WD20EARX SATA 3 drive on a SuperMicro AOC-USAS2-L8i (SAS 6G) controller (flashed with -IT firmware). I'll continue this in the -CURRENT list in the thread about the new driver as that's where the main discussion has been.
