Problem Description: 

SS10-51 or SS600-51 systems may occassionally fail with "watchdog
reset" or hard hang. This patch provides  fixes specific to
SS10-51 and SS600-51 configurations and requires patchid 100726-12
to be installed. 


Patch Installation Instructions:
--------------------------------
1. As root, run the "installfix" program as follows :

	# sh sun4m/installfix

   If the /vmunix file cannot be found or patchid 100726-12 was not installed
   previously, the program will generate the following error message 

	"installfix: /vmunix not found or patch 100726-12 or higher 
	 has not been applied to this system"

   In the event of the above error message,the kernel should be renamed vmunix or
   if the kernel is /vmunix,then patchid 100726-12 needs to be applied prior to 
   installing this patch.  

2. Reboot the system.

   IMPORTANT NOTE: This patch must be re-installed if a new /vmunix is created.
   Installation of other patches or reconfiguring the kernel may require a new
   /vmunix to be built.  This patch will need to be re-installed each time after
   a new /vmunix is created.

To backout the patch:

1. As root , run the "backoutfix" program

	# sh sun4m/backoutfix

2. Reboot the system.
