Interrupt storm on atapci1+

Hi all,

I currently running a FreeBSD-CURRENT on a Intel Core 2 Duo and I seem I
have a interrupt storm which take approximately 90% of a CPU.

This is the vmstat -i
nicolas_at_marcellus:~%vmstat -i
interrupt                          total       rate
irq1: atkbd0                        2508          0
irq17: mskc0                      133918          6
irq19: fwohci0+                     8288          0
irq22: atapci1+               1174121373      61321
irq23: uhci3 ehci1                     1          0
cpu0: timer                     38250554       1997
cpu1: timer                     38240647       1997
Total                         1250757289      65323

I give you my kernel conf.

I don't really know what informations can be useful so feel free to ask
anything you need.

Cheers,
