Have you tried provoking it with heavy network, or memory usage, or disk activity? I have an IPX with a weitek powerUp! cpu + rom that was aaround 2003 getting a bit on the unstable side with similar lock-ups. I ended up de-soldering and re-capping the entire board + PSU, and thus far touch wood it's not sneezed. Another thing that may be worth thinking about is an expect script or perl script driving the serial device that'll send escape sequences through?So it crashed in a day this time. I tried to get the ctrace data but it was taking forever to transcribe so I decided to scrap that for the moment and rebuild the kernel with debugging turned on including console messages and every other debugging feature enabled. I'll use that one and see what happens. At least I'll have a symbol table so I'm not staring at a list of jumps and calls.
Crash in less than a day. I was in the middle of compiling the new kernel with debugging enabled when it bombed.
This time I just captured the ctrace data though I still intend to compile the debugging kernel. I'm hoping some of you can help me make sense of the ctrace dump. The interesting thing is that it fails in exactly the same spot. The PC always stops at ffeaf538 the last three times that I was able to do a ctrace. I don't remember if the other instructions are identical but I know the PC is.
