My guess is that it comes from the ahci_dma_setup() call failing in
ahci_atapi_start(). Can you add some printfs here to confirm, and
see what with what values ahci_dma_setup() was called ?
Another candidate would be scsipi_request_sense().
Another place where XS_DRIVER_STUFFUP is used is scsipi_enqueue()
but this shouldn't happen.
