I got the same query, but for ata20.0

It might be tied to the discovery of a dvd-writer on the sata cable. At least it seems to follow with attaching scsi 19 as sg10
(I have no abort, but still a red exception and cmd for ata20.00

Title:
  Weird HW exceptions after upgrading to 14.10

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to Ubuntu 14.10 I can see these worrying lines,
  printed in red, from my `dmesg` output:

  [ 3.192349] ata14.00: exception Emask 0x1 SAct 0x0 SErr 0x0 action 0x6 <-- printed in red
  [ 3.192395] ata14.00: irq_stat 0x40000001 <-- printed in red
  [ 3.192436] scsi 13:0:0:0: CDB:

           res 00/00:00:00:00:00/00:00:00:00:00/00 Emask 0x3 (HSM violation) <-- printed in red
  [ 3.192505] ata14: hard resetting link

  [ 3.520696] ata14.00: configured for UDMA/66
  [ 3.520821] ata14: EH complete

  Any ideas where the exception and HSM violation is coming from?

  The next section with a similar issue is:

  [   14.172661] ata8.00: exception Emask 0x1 SAct 0x0 SErr 0x0 action 0x0 <-- printed in red
  [   14.172712] ata8.00: irq_stat 0x40000001 <-- printed in red
  [   14.172754] ata8.00: failed command: SET FEATURES <-- printed in red
  [   14.172817] ata8.00: cmd ef/05:fe:00:00:00/00:00:00:00:00/40 tag 18
           res 51/04:fe:00:00:00/00:00:00:00:00/40 Emask 0x1 (device error) <-- printed in red
  [   14.172879] ata8.00: status: { DRDY ERR }
  [   14.172922] ata8.00: error: { ABRT }

  Been searching everywhere for solutions but found no working one. Any
  clues? Any answers very welcome.

  Thanks!!
