Quick follow up: I decided to disable the DMA controller as a near term solution. This works but it is not optimal for obvious reasons.
I believe that the chipset initialization for utilizing the DMA controller is incorrectly setup, for the particular model I am using (CMD 648). I don't know when/if I will look into this further. For more information regarding my analysis of the problem refer to my first email, with the email subject as "IDE CMD 64x PCI driver." -Rob - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
