Turning _off_ disk fma and then totally replacing the driver with one that doesn't support fma were definitely not the recommended actions! Given the rest of this thread, I'm really keen to see (as somebody who works on mpt(7d)) how your system behaves with fixed SSD firmware, using mpt(7d) and with disk fma turned on again. After that, let's talk about "broken" drivers. James C.
