Can you provide what ATA chipset this drive is connected to?  The
drive appears to be associated with ata2.  The following may suffice,
for example:

$ dmesg | grep ata2
ata2: <ATA channel 0> on atapci1
ad4: 114473MB <Seagate ST3120827AS 3.42> at ata2-master SATA150

$ dmesg | grep atapci1
atapci1: <nVidia nForce CK804 SATA300 controller> port 0x9f0-0x9f7,0xbf0-0xbf3,0x970-0x977,0xb70-0xb73,0xd800-0xd80f mem 0xd3002000-0xd3002fff irq 23 at device 7.0 on pci0
ata2: <ATA channel 0> on atapci1
ata3: <ATA channel 1> on atapci1

Additionally, please provide the output of `vmstat -i` to see
if there's any shared interrupts with the ATA controller.
