"Me too" - when I enable DMA it's not long before the system stops responding altogether. Without DMA, I get a data read rate of about 800KBps.
But also, I have two identical drives attached - hda and hde (both ST380023AS). Even if I don't turn on DMA, if I am using both fairly intensively at the same time (at least that's the only thing I can identify as an apparent common difference), one will (on random occasions) start returning errors for every access. If this happens to be the drive that the operating system is installed on, the result is somewhat fatal. If it's the other drive I can continue, but any attempt to access it fails. There are some syslog entries that appear to relate to this:
