I posted the following message just over an hour ago, and I am already
posting the summary! The fix is to apply patch #100232-01.
My original message:
>We have been having some problems with sparc-2's, 16MB, SunOS 4.1.1.
>This has happened both on mono and colour sparc-2 workstations. This
>has not happened on any of our sun-3, sparc-1, sparc-1+, slc or ipc.
>The workstations quite frequently freezes. The symptoms are:
> 1. The screen goes blank.
> 2. All of the LED's on the keyboard are off
> 3. The green LED on the cpu box is off.
> 4. Cannot even rlogin
> 5. The L1-A does not work and the workstation has to be switched
> off/on to reboot.
>This happens even when a user is using the workstation at the console
>(rules out screen blank problems). This has happened both with
>OpenWindows and SunView environment. Anyone seen this before? Any
