160GB, 80GB & 40GB

grep .  /proc/irq/*/*/threaded

then 

echo "0" > /proc/irq/9/hdsp/threaded

except change the number from 9 to whereever your hdsp resides. On my
machine I'm set like this:

[root@Godzilla root]# grep .  /proc/irq/*/*/threaded
/proc/irq/10/ehci_hcd/threaded:1
/proc/irq/10/eth0/threaded:1
/proc/irq/10/ohci1394/threaded:1
/proc/irq/10/uhci_hcd/threaded:1
/proc/irq/11/ohci1394/threaded:1
/proc/irq/12/i8042/threaded:1
/proc/irq/14/ide0/threaded:1
/proc/irq/15/ide1/threaded:1
