I'm running 3.2-stable, which is identified as 3.3-RC on my system right now. You can see my mix below and I'm not having any problems with DMA and WD. On the old SuperMicron P5STE motherboard, I couldn't eliminate the normal MBR on the WD drives with out hanging the system at the boot. I figured that it was something between the "dangerously dedicated MBR" and S.M.A.R.T. on the WD HD's. The motherboard at this point is a ASUS P2B-B. The system had 3 - WD HD's on it at one point. I haven't tried a WD ATA-66 drive like the AC29100 on this system. There is something going on between your MB and that HD. Does the GB AX have a 66MB/s IDE interface on it or are you using something like the Promise card?
