- Does it also fail if you use the Promise channels instead ?

There is NOT a failure if both drives are on the Promise controller.  There
is also NOT a failure if both drives are on the motherboard IF I turn off
HyperThreading in the BIOS.  The failure happens if both drives are on the
motherboard and HyperThreading is on.
