I have been running my machine mostly configured for pciex1 thus with the sata_dwc disabled. The changes to sata_dwc-460ex do cause an oops. I will try to give more detailed info over this weekend .The driver as is upstream would do that since it unconditionally dereferences a null pointer in the probe function. My patch fixes that as a side-effect.patching file drivers/ata/Kconfig Hunk #1 FAILED at 296.
