  Log:
  MFC: 1.36
  Allow Cyrix 5530 based UltraDMA IDE controllers to co-exist with other
  devices on the PCI bus.
  This is a workaround for a bug in the Cx5530 PCI bus logic that will
  hog the PCI bus if the disk is fast enough. UDMA mode 2 is fast enough
  to make this happen so limit the drives to mode 1. The symptom is
  missed interrupts and sio  silo overflows at high async speeds.
