Just another data point, for what it's worth.
I've got one of these puppies that works perfectly except I cannot enable DMA on the CD-RW drive. I normally run a vanilla 2.4.19 kernel, but it also works fine with the RedHat 8.0 kernel (whatever that is?). I only have one hard disk at the moment (80GB WD) but before the old one died, I routinely copied 800 MB files (video) between disks with no errors. The CD burner works fine at 16X. I'm running an AMD K6-III 350 with a 25 Mhz overclock, rock solid. The MB is a FIC VIA 503+.
A normal load on the machine is a continuous 200KB/sec download on the cable modem using PAN, XMMS, Firebird, and Sylpheed. XMMS skips are very rare! Mplayer works great with a few dropped frames on really high res DIVX video.
So I don't think you can point the finger at the MVP3 chipset.

I'll be happy to supply any info that can help anyone. I know this problem has been bugging people for a long time.
