I've been following this thread for quite a while - I have been getting DMA timeout errors on boot for about a year - i am also running SMART and every test I have done shows no problem. Booted with the install disk and run fschk so many time I have lost track. Never a problem, but DMA timeouts continue. I have come to the conclusion it's some obscure bug, perhaps in the IDE module. It *never* affects anything else as the drive is fast and so far reliable. If/when it dies I'll change my opinion. -- Change the world one loan at a time - visit Kiva.org to find out how
