[issue1158] Problems with a SATA DVD burner

	Same result on HEAD as with the patch - interrupt storm starts with
the second burn and continues as long as something tries to talk to the
drive. This is a big improvement over the original state of affairs where
the interrupt storm started during booting and didn't go away at all. It
may well be enough for some chipsets - wider testing is I think in order.

	Also I get interrupt storms if I boot with atapicd enabled and no
atapicam whether or not I have DMA enabled.

	I now have a hardware workaround (just arrived in the post) in the
shape of a bi-directional PATA/SATA adaptor but I'll happily test any
patches or updates.

	Thank you very much for looking at this.
