===> FOR I/OAT DMA
Latest status, it _appears_ its working on the X9SRL-F now, thank you!

1) Supermicro X9SRL-F (GOOD)

It is _not_ working on the:

2) Supermicro X8DTH-F (the boot drive in this system is running off a PCI-e
card, could the IRQ for the I/O controller be getting re-mapped and fail?)--
worse case I can move the SSD from the 6.0gbpa SATA card to the motherboard
and see if that works, but that kind of defeats the purpose of a 6.0gbps
SATA SSD.

Would be curious if anyone had any suggestions besides removing the
controller card?

==> Further issues with the X9SRL-F -- does this board support ASPM or is
this a Linux/ASPM implementation issue?
