Well, I'm back. In mid-March I posted a message or two about my computer
crashing and knocking Linux out. I had hoped to get Linux back up without
resorting to reinstalling it, but eventually succumbed to reinstalling,
thereby calling a halt to the problem. This seemed to have cured the problem
but what actually happened is that I could no longer build a real time
kernel, rtlinux, successfully. This had nothing to do with the PS or
hardware. After a long struggle lasting into early Sept. with the build,
someone discovered a serious problem in the kernel build makefile. A few
weeks ago, I was running the intended application again.
Note that I never had the computer on a 24/7 operation for days on end
during this lengthy shakedown of the makefile problem.
About four days after 24/7 op with rtlinux and app now working, the computer
went down without explanation. I successfully rebooted, and started the app
again the day I left for a two week vacation. I called my wife 3 days into
the vacation to check the operation, and the computer was down. She could
not reboot it.
As I was driving back two days ago thinking about the problem, it occurred
to me that it has to be the PS. When I bought the computer chassis/PS almost
22 months ago, I got a discount, since the chassis had been dropped. The
exterior damage was slight, and I got that squared away fairly easily. The
exterior damage was mostly that it was hard to get the chassis open. Some
screw driver prying and pushing fixed that. For all practical appearances,
the PS was functioning properly. I now suspect the damage was much more
serious, and bought a new PS today. I can't think of any other explanation.
It's just too bizarre. I'm going to try it in the next 24 hours. Stay tuned.
