gcscide —
gcscide* at pci? dev ? function ? flags 0x0000
gcscide driver supports the IDE controller of the
  AMD CS5535 Companion device, and provides the interface with the hardware for
  the ata(4) driver.
The 0x0002 flag forces the gcscide driver
    to disable DMA on chipsets for which DMA would normally be enabled. This can
    be used as a debugging aid, or to work around problems where the IDE
    controller is wired up to the system incorrectly.
