This problem is already fixed in Linus' tree -- somebody just needs to
port it to 2.6.29 and then post it to stable@...nel.org for inclusion.

Subject: [PATCH] cs5536: define dma_sff_read_status() method

The driver somehow got merged with the initializer for the dma_sff_read_status()
method missing which caused kernel panic on bootup.

This should fix the kernel.org bug #13026...
