I found the culprit.  It seems that ata_port_reset identifies the
device, and if it has power up in standby enabled, and requires the
SET FEATURES command to spin up, issues the command right away.  I wonder:

1)  If the spinup command can't be delayed until the disk is actually
accessed and/or

2)  If the disk is in runtime suspend when the system is suspended,
why doesn't it remain suspended when the system is resumed, thus
delaying the port reset until the runtime suspend is lifted ( when the
disk is accessed ).
