I am not an ATA expert either, but this sounds like the problem I
investigated at a previous employer.  When resuming from S3, the hard
drive password has to be resubmitted to the drive since it was powered
down during the S3 "shutdown".

In order to avoid the time it takes to initialize the ATA subsystem, if
a password was not set, we just skipped initializing the subsystem.  But
we had to initialize it and submit the password to each drive if one was
set.  This sounds like what is happening (or not happening) in this
report.

Later we found that we had to initialize the ATA subsystem and "freeze"
the hard drive password to prevent the OS or 3rd party tools from
setting up the hard drive password if the password was not set (this is
because we hashed the password to prevent the drive from being moved to
another system and hacked if the user had a reasonably easy password
("MyInspiron", for example; and the other tools do not know the hashing
algorithm).
