Hi Clemens,
How did you disabled the DMA ?

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,
