Problem Description: 

THIS PATCH DOES NOT APPLY TO 4.1.1, 4.1.2, 4.1.3, 4.1.3_U1, CMW 1.0, OR
TRUSTED SOLARIS 1.1 SYSTEMS.

This patch contains a fix for the following bug(s):

Note:	In the following lists of files, the export/exec path prefix is
	used to load files into the appropriate places on the machine.
	For example, export/exec/kvm/<arch> is used to refer to
	/usr/kvm on a machine where <arch> is the native architecture.

Bug:	4089720
Desc:	panic occurs during acl_rw() because of dangling ACL inode
	reference. Modifications were made to the kernel to detect
	the dangling reference and to clear it. fsck was also modified
	to detect this condition and correct it on disk.

Files:	<path_relative_to_root_directory>
        export/exec/kvm/sun4/sys/sun4/OBJ/ufs_inode.o
        export/exec/kvm/sun4c/sys/sun4c/OBJ/ufs_inode.o

Patch Installation Instructions: 

1.	Boot the machine single user, clean the disks, and start a csh(1).

		> b -s
	or
		ok boot -s

		# fsck -f -p
		# exec csh
		<host># source /.cshrc
		<host># source /.login

2.	Load this patch in a location that has disk space.  This
	example assumes that /var is a separate partition and that
	the patch is delivered on tape.

	<host># mount /var
	<host># cd /var
	<host># mkdir -p patches/SFD106732-01
	<host># cd patches/SFD106732-01
	<host># tar xvf /dev/rst0

3.	Install the patch and check the "log" for errors.
	<host># ./install_patch |& tee log
	<host># vi log

3a.	This patch contains changes to the machine's kernel. In order
	for the changes to take effect, the kernel must be reconfigured.

	To reconfigure the kernel, follow the procedure in the README
	file, located in the /export/exec/kvm/<arch>/sys/<arch>/conf 
	directory for each architecture.

4.	Reboot the machine.
	<host># cd /
	<host># umount -at cfs
	<host># sync; sync; sync; reboot
