Path Name: /hp-ux_patches/s700_800/10.X/PHNE_11667

Symptoms:
	PHNE_11667:
	UPS failed to work on EISA mux in by-pass mode.
	Select interface failed to work on EISA mux in by-pass mode.

	PHNE_9026:
	VTIME > 0, VMIN = 0 caused raw mode read to return
	in less time than specified in VTIME.
	VsiFax software failed to work due to above
	VTIME/VMIN problem.
	Select system call hangs on EISA mux port.
	Screen froze when running telnet on EISA mux port
	due to the above failure on the select system call.

Defect Description:
	PHNE_11667:
	This problem was casued by a logic error in the by-pass
	mode select interface.

	PHNE_9026:
	The first problem was caused by a logic error in the
	by-pass mode of the EISA mux driver handling the
	VTIME > 0 and VMIN = 0 case incorrectly.
	The second problem was caused by the fact that the
	driver was mistakenly sleeping on the process instead
	of the kernel thread.

Installation Instructions:
	Please review all instructions and the Hewlett-Packard
	SupportLine User Guide or your Hewlett-Packard support terms
	and conditions for precautions, scope of license,
	restrictions, and, limitation of liability and warranties,
	before installing this patch.
	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHNE_11667

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_11667.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHNE_11667.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHNE_11667.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHNE_11667.text file to
	/var/adm/sw/patch for future reference.

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

		dd if=/tmp/PHNE_11667.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	Install this patch only on a system that equips
	with an EIAS bus and with an EISA mux card installed.
