I have a single Promise PCI IDE controller, but I don't have any hard
drives hooked up to it. /dev/hda and all the SATA drives are hooked up
to the onboard nVidia controllers.

My motherboard is a "DFI LanParty UT nf3 250Gb" (despite the unwieldy
name, it's a rather nice board) and I think it dates back to August
2004. I built my machine in November 2004, and I've never had an IDE or
SATA problem with it.

I started testing (and then using) my RAID-5 in May 2006 with Linux
2.6.16. I built the array degraded, so I know that resync worked for me
then. So did restriping, which I did twice. Since then, I've run 2.6.17
and 2.6.19, without any problems.

Thanks,
Corey
