[--the same repeats--]
Actually, my 20360 + PX-716SA combination is worse. It shows the same
behavior during device detection.

Justin, this seems very similar to the problem which occurs when PMP
is attached. This one is very reproducible too. Just boot up
libata-dev#upstream and connect PX716-SA. Any ideas?
Thanks.

I dont suppose the recent email to linux-ide with subject "libata: fix
ATA passthrough handling for ATAPI devices" might help resolve this?
these are atapi devices and we are using libata after all..
