What gives you the impression that there was some "synchronization with
the software"? Nothing NW_Pilot reported would suggest it, and the
frequency and number of reboots implies something completely different.
His description suggests that the system booted and went through the
same software process over and over. That is not a hardware problem.
Care to put some money on that conclusion? Many, many years ago we
encountered a similar problem. Every symptom said it was software,
especially when one operating system would not encounter the problem yet
another one did. After several weeks we managed to isolate the exact
channel program sequence which caused the error. The hardware developers
confirmed that the channel program sequence was indeed valid. Further
investigation showed it to be an error in a circuit card supplied with a
field upgrade kit. Since each operating system used a slightly different
channel program to accomplish the same thing, the error only manifested
itself on one system.
