Your setup > is intriguing in that the BIOS has chosen to leave the drives in PIO > mode As an extra datapoint I have very a very similar problem with a WD360 drive and an siimage 3112 PCI controller on a shuttle (via-based) AK31V2.0 motherboard. The sii3112 interfaces show up as ide0 and ide1 (can that be changed?) using MMIO-DMA/pio. Testing the drive as-is results in ~3.5MB/s transfer rates (via hdparm -t), and attempting to enable DMA via "hdparm -d 1" results in an immediate lockup the next time the drive is accessed. When I get another chance, I'll probably try the two fixes others in this thread have suggested: hdparm -X66 -d1 /dev/hda and if that still has trouble under load, someone suggested: echo "max_kb_per_request:15" > /proc/ide/hda/settings Hope this helps.
