PROBLEM: (75340, 77361, 77425, 79767) (PATCH ID: OSF445-091)
********
This patch corrects the following problems with some models of IDE CD-ROM
and removable disk devices during system startup:
    - Some IDE CD-ROMs may cause a system panic, with  "kernel memory fault"
       during a bus device reset.

    - Some IDE master devices require special code when they are
      configured as the IDE master with a non-existant slave device.
      This could cause a
	"xpt_callback_thread: callback queue corrupted" panic.

    - Playing the last audio track of an enhanced CD may cause
      unpredictable system slow-downs or temporary system hangs.
