The problem actually has been spotted on sata_nv. It is suggested that
this is dependent on what type of device is attached to the controller.
This problem seems to be caused if the device is slow to ack the first
H2D Register FIS. So, we really don't know which controllers are
affected by this.
How about doing msleep(1) if it's SATA?
Given the minimal amount of problem reports, I'd rather hold off and
collect data. What devices are affected? Is it complaining because
it's in the middle of a reset when SRST is received? Is it just one
model of one device? Is this definitely reproducible on all SATA
controllers? etc.
Too many unknowns right now...
