	Something happened with ncq's sata_nv support. When I halt my
system (Athlon64, Asus M2N-E), I get the following (I had to copy by
hand, since the system is halted, so it's just an excerpt):

IRQ 21: nobody cared (try booting with the "irqpool" option)
Pid 0, comm: swapper not tainted 2.6.26 #2

Call trace:
........... nv_swncq_interrupt
........... __report_bad_irq
........... note_interrupt
........... handle_fasteoi_irq
........... do_irq
........... ret_from_intr

Handles:

[<f88888888803a5b90>] (nv_swncq_interrupt+0x0/0xd0)

Disabling IRQ #21

	This just happens after a halt.

	If I use irqpool, this error doesn't happen.

	Thanks.
