Again, sorry for the delays in my replies.  I'll try to get to the rest

Can you mount and read cd/dvd media normally with DMA enabled?

Are we dealing with a piece of hardware that's too brain damaged to live?

If the entire line of drives is incapable of DMA at any time, then it 
would seem to me that the kernel should blacklist it, and we should never 
have to deal with this situation.

If it's just that specific drive that doesn't work, then it should be 
replaced...

I'm not sure the kernel shouldn't be responsible for disabling DMA as soon 
as a transfer fails.

What make/model of drive is it?
