Symptoms:
	PHKL_15955:
	Problem occurs when a kernel is built with both autox0
	and ssrfc in the system file. This causes the bdevsw
	and cdevsw functions for disc3 the be changed that
	leads to the failure in vgcreate(lvm), so whenever the
	boot device uses disc3 driver, the system will be
	halted in the boot process.

	PHKL_14425:
	The system will panic during boot, if a 8X MO autochanger is
	connected to it.

Defect Description:
	PHKL_15955:
	In autox0 driver, autox0_install routine replaces
	cdevsw[177].d_open with autox0_pseudo_copen and
	replaces bdevsw[28].d_open with autox0_pseudo_bopen. This
	replacement breaks the assumption of the same routine for
	raw device and character device.
	In block_to_raw, it attempts to locate and return the
	matching raw device for the supplied block device by
	using above assumption.

	PHKL_14425:
	Since the data returned from a 8X drive is at least 14 bytes
	more than 4X/2X drive, autox0 driver does not allocate
	enough space to store it and it overwites the kernel's data
	which causes the system panic.  To resolve this, two data
	structures in autox0.h were changed to have more bytes.
