[issue566] NATA a nonstarter with ATI SB600 on MSI K9AGM-FID

["Joe \"Floid\" Kanowitz" <bugs@xxxxxxxxxxxxxxxxxxxxxxx>]

New submission from Joe "Floid" Kanowitz <jkanowitz@snet.net>:

As I've been rambling about on the blawg --
http://www.shiningsilence.com/dbsdlog/index.php/2007/02/23/2143.html -- turns
out using February 24, 2007's HEAD with NATA enabled refuses to boot off my
drive hooked onto the SB600's parallel ATA port.

Using the NATA kernel (nata, natadisk, natapicd, natausb, nataraid enabled; no
atapicam; options PCI_MAP_FIXUP set), the system recognizes ATA controllers
present, including atapci0, finds and reports ad0's identification string,
announces its attempt to mount root from ad0s1a, then hangs without a blink from
the controller's activity LED.

In my brief testing with the 1.9.0 kernel, I've seen boots where it gets 'stuck'
quietly at that point, and boots where it would announce a segmentation fault in
init every 30 seconds.
