Thought I should share the experiences I have had with JM20330 mSATA adapters.
At least in kick 3.0 and 3.1, there appears to be some very early check done in scsi.device which the JM20330 is not booting fast enough to answer to correctly. It is not the spin-up wait which is in seconds (8s on 3.0, 30 on 3.1), but something way earlier: if you add say a Blizzard1230 or 1260 the JM20330 adapter will start work, I guess because those accelerators add a small delay when doing it’s initialization and rainbow-effect very early before scsi.device starts executing.
Cutting the RESET line on the JM20330 board (pin 1 on IDE <-> JM20330 chip) so it doesn’t reset when the Amiga resets makes it work after warm boot, but you still have no drive on cold boot.
Don’t remember if 3.1.4 or 3.2 fixes this, but it is possible as it is very slow to init scsi.device.
