Hm, cool. I wonder if it's at all similar to the Acer UDMA engine, which btw I seem to have at least partially working at this point. (Streaming transfers -- i.e. dd if=/dev/rwd0 of=/dev/null -- work, but if you, say, run fsck or boot the system multi-user, it'll work fine for a few seconds, then get some interrupt timeouts, then work again for a bit, then the cycle repeats. I think the UDMA cycle time needs to be tweaked, but I'm not sure.) > Unfortunatly the 5530 UDMA engine has some serious bugs. > some of which can't be worked around from ide_pci.c alone..
