Well, here is the interpretation of messages:

Your SATA hardware flags a connect-or-disconnect event ("PHY RDY"), 
which requires us to abort a bunch of queued commands:

  ...through the 14th command (tag 13).

SATA link is reset, and ACPI is re-run.

The SCSI subsystem aborts each of the queued commands.

ext4 pukes, because of SATA/SCSI errors

SCSI finished re-initialization.

So from this, a few observations and open questions:

Why didn't these SCSI commands get retried?

Were they left over from prior to resume?

Did SCSI error out the commands too soon?  The probing is not complete 
until AFTER the sector errors, I note.

Did the system resume before ACPI resume and SCSI resume completed?  It 
sure looks that way, from the log.

Does the asynchronous probing play a role here?

It looks like there are a few different scenarios in what could happen:

I had another go at hibernating on 2.6.29 running with and without X,
and this time round it resumed with a *clean* file-system. Without X, it
looked to be better off as there were not even any ATA errors logged,
but I'm not sure if this is just because of the system being almost
entirely idle.

Going on your comments of earlier, when hibernating in X it looks like
this time the SCSI initialization completes normally before any errors, 
being 'ATA bus error' messages for a while until a hard reset occurs.

I've attached the messages from both, hopefully this gives someone more
of a clue of what is happening.

cheers
Niel

No .. this is the SCSI subsystem receives an ABORTED COMMAND return in
sense data for each of the outstanding I/Os

The only place these are generated is in ata_sense_to_error() which only
occurs if there's some type of ata error.

If I had to theorise, I'd say the system suspended with commands
outstanding to the device.  On resume, the device gets reset and returns
some type of ATA error which gets translated to ABORTED COMMAND which
causes a failure.

In the mid layer, we translate ABORTED_COMMAND into a retry until the
command runs out of them ... could it be there's a race readying the
device and we run through the retries before it can accept the command?
