Symptoms:
	PHKL_22975:
	( SR: 8606165678  CR: JAGad34969 )
	Kernel panic may occur on servers (L3000 only known case
	currently) with a VISUALIZE-FXE graphics card installed.

	Panic stack trace:

	    panic+0x14
	    hdl_pfault+0x660
	    pfault+0x104
	    trap+0x4ec
	    nokgdb+0x8

Defect Description:
	PHKL_22975:
	( SR: 8606165678  CR: JAGad34969 )
	32-bit IO Blocks for IO adapters (graphics in particular)
	may be mapped in to 32-bit address space at some value
	other than in the upper 256 MB (addresses beginning with
	0xF).  If this happens, a protection fault will occur
	if the system attempts to use that region of memory for
	something other than I/O (shared memory access, in
	particular).

	Resolution:
	Code was added to remap io blocks down into the upper
	part of 32-bit IO space, even if the lower 32 bits are
	not in 32-bit IO space (addresses beginning with 0xF).

SR:
	8606165678

Other Dependencies:
	The patch PHKL_22976 should be installed, along with this
	one, on server systems that use graphics cards.  If only
	this patch is installed, but not PHKL_22976 or a successor,
	then the panic is still possible, although a warning
	message will be place in the system message buffer.

	/var/adm/sw/save/PHKL_22975.  If you do not wish to retain a
	copy of the original software, use the patch_save_files option:

		swinstall -x autoreboot=true -x patch_match_target=true \
			  -x patch_save_files=false -s /tmp/PHKL_22975.depot

	WARNING: If patch_save_files is false when a patch is installed,
		 the patch cannot be deinstalled.  Please be careful
		 when using this feature.

	For future reference, the contents of the PHKL_22975.text file is 
	available in the product readme:

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHKL_22975.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	This patch depends on base patch PHKL_18543.
	For successful installation please insure that PHKL_18543
	is already installed, or that PHKL_18543 is included
	in the same depot with this patch and PHKL_18543
	is selected for installation.
