The folloing is the posting and the as-usual-prompt response from the sun-managers........The overwhelming majority of the response was that I have a problem
with either Mouse or Keyboard or the Cables associated with them...And that was
really the source of the problem.....A couple of them suggested to install
recommended patches........
Thanks to all of you....
I am still receiving messages about this posting...........So, I apologize if
I have missed somebody...........
I posted on Nov.2, 1994:
Hi:
On one of my Sparc-10/41 ( Sun 4.1.3.), every few minutes, the machine
seems to be halting with the following:
Type 'go' to resume
ok
At this point I lose all control to the windowing environment..When I type 'go', it starts again....It happens usually when there is keyboard or mouse activity....If the machine is left to itself, it works fine..
Any clue to the source of this problem will be helpful...
Thanx..

This sounds like a problem with your keyboard. More specifically,
the connection between your keyboard cable and the keyboard itself.
Try changing the keyboard and/or the cable.

More clues as to your setup would be helpful. Is this 4.1.3, 4.1.3u1A,
or 4.1.3u1B?? What patches have been installed?
At any rate, I think you need to upgrade the OS to at least 4.1.3U1revB,
or consider going to 2.3...

A couple of times we've had bad (type 4) keyboards which would
apparently generate the <STOP>-A sequence by themselves. This would
happen when someone was logging in or out under X11R5 since at that
time the keyboard gets reset (all the lights flash on and off). It
could be that your keyboard has even worse problems and is frequently
generating <STOP>-A by itself while in use. Even simpler, are all the
keyboard leads firmly in place? If you have another machine, just try
swapping the keyboard and see if the problem goes away or follows the
keyboard.

Check to make sure you don't have a loose keyboard or mouse cable.

Check the physical connections on both the mouse and the keyboard. I've seen this happen lots of times when the plug is somewhat loose, and jiggling it sends the system a false L1-A signal.

Check for a bad or loose keyboard connection. Generally if you remove and then re-connect the keyboard this will generate a break signal (equivalent to L1-A). The newer type 5 keyboards are particularly prone to this I think because they don't have a cable anchor like the older type 4's.

Hello Amitesh,
look for the plug of the keyboard. If the plug is unplugged and replugged again, a Sun machine is usually going to the "halt" state, which could be resumed with the "go" command. So check the connecting and try to fix the keyboard plug.
Hope it helps, Dirk.

I don't know if this is the problem, but when you unplug and then plug in the keyboard, the Sparc 10 will drop to the ok prompt. Therefore, maybe your keyboard cable is not connecting properly or is loose.

Either the keyboard cable or the mouse cable is loose.

Hello; at first test your keyboard or mouse itself. Exchange it with another machinne if possible. We have had the same behavior of a machine and the reason was a defect in the mouse cable. It was broken (but not completely) and so it produced wrong characters.

Hi Amitesh,
To solve your problem, you need to install all the mandatory patches for SunOS 4.1.3 or if you can, install the SunOS 4.1.3_U1 + the mandatory patches. The most important is the 101508-xx, this is a kernel jumbo patch for all the sun4m architectures
For SunOS 4.1.3, I give you below the mandatory patches :
100513-xx 100726-xx 100173-xx 100359-xx 100338-xx <-- system crashes with assertion failed panic 101071-xx 100305-xx 100557-xx 100623-xx 101408-xx <-- SS10-51 may hard hang or watchdog reset
I think your problem will be solved after the installation of these patches.
Best Regards,
Yves Hardy from AB Computers in Belgium. ******************************************************************************
>From mgaertne@igd.fhg.de Thu Nov 3 02:15:03 1994 Hello, this behaviour is most likely a hardware-problem. First suggestion: check the keyboard-cable and the mouse cable. If they're a little bit loose and you shake them, they halt the cpu in the matter you've seen. I experienced a lot of keyboards with loose connectors on suns (we have 122 of them :-) )
Hope that helps

Check the keyboard and mouse cables, if you unplug either of these while the system is running, the workstation will jump to the PROM monitor (Type 'go' to resume).
Try using another workstation's cable

Inspect Keyboard and Mouse Cabling, reseat Connectors, etc.. What you see is the usual Reaction of a SUN to getting a Keyboard plugged in (when there was none before, or it had been unplugged). The Hardware Version of pressing L1-A. Try swapping in another Keyboard if Cabling doesn't cure it.

When the keyboard is disconnected from the sparc and then reconnected, you'll see this behaviour (note, it happens when the cable is *reconnected*). As it happens when there is keyboard activity, I'd suggest either a faulty keyboard, or more likely, a faulty or improperly seated cable.
Hope this helps,
Steve.

If you remove...THEN REPLACE...a keyboard connection, the system will halt just like you said. My guess is that you have a keyboard (either end) cable that is loose, or some broken connection...try and different keyboard and/or cable. -- #### ###### Gene Loriot E-mail: epl@Kodak.COM ### ######## Eastman Kodak Company Voice: (716) 724-6962 ## ########## Customer Equipment Services Fax: (716) 724-9860 # ### KODAK ## 343 State Street ## ########## Mail Code: 00708 ### ######## Rochester, New York 14650-0708 #### ###### U.
