Hello, David, Jeff!

I'm using a PDC20269 (on Promise Ultra133TX2 card) w/ DMA disabled on
an embedded ppc (MPC8540). I cannot use DMA, too.
I guess it's a PCI IRQ/REQ/GNT problem on my board.
With DMA disabled I haven't had any problems on my system.
I am going to use a PDC20275 in the future.

My .config of a linux-2.6.13-rc7 is attached.

And... I know other guys with similar problems on embedded environments.
Unfortunately I wasn't able to have a closer look at this problem yet.

Best greets,
