So a 30 second glance says that the problem is that you seem to have dma_mode uninitialised as zero which is bogus. That means either ata_acpi_gtm_xfermask broke (it should have set the bits to 0xFF if no mode is found), ata_dma_enabled is broken, or pacpi_qc_issue got called before pacpi_port_start (which seems wildly unlikely) Needs someone to go and dump the relevant values in the right places and see what is breaking in the pata_acpi setup logic.
