This message is from the T13 list server.
I believe it is in the spec state machines, but any command other than Read
DMA Queued or Write DMA Queued will be aborted if the queue is not empty.
It will also cause the queue to abort.

[t13] Queued DMA Command

Hello,
On a SATA link with devices that support command queuing, can a DMA QUEUED
command (read or write) and a DMA non-queued command be pending at the same
time? In other words, Can a SATA Host send a READ DMA QUEUED followed by a
READ DMA while the first command is pending?
If not, can anyone point me to the spec that says so?
Thanks,
Yamini
