i have this problem on my IBM Deskstar 7200RPM drives (one in a Apple
G3 the other in an intel box) the closest i have come is:

/sbin/hdparm -S 0 /dev/hda which seems to make it happen less (maybe,
its supposed to make it happen not at all) but I have noticed that
while the drive still sleeps once in awhile i no longer get the DMA
errors under 2.2.15 like i did with 2.2.14.  

wtih 2.2.14 i could intentionally put it to sleep and it get that
error when it wakes, no more on 2.2.15.  

i also run /sbin/hdparm -k 1 /dev/hda at boot as well so that i don't
lose DMA after one of those errors, which makes the disk performance
slow as snot.

read man hdparm for more info.
