Hi Jim,

	I think it's not a answer to you but here is my recent experience.
	I've installed FBSD 5.4 in a box with Intel ICH5R chipset.
	It's working, no hangs, no panics, but the disk performance on the
second IDE disk (I'm not using RAID, just simple master/slave setup), is
	It's like the DMA was not correctly set on the second disk.
	I read somewhere, that FreeBSD has full support to ICH5 chipset
but NOT for ICH5"R".
	Even when running in "compatibility mode" set on BIOS, the
performance is the same.

	Someone told me the follwing on the performance list:

	"I remember a commit to the ata driver to fix misprogramming of
DMA timing on an Intel chipset for devices and/or channels other than the
first.  I'm not sure if 5.4 has the bug or the fix."

	To me it still has the bug.
