I had 32MB of RAM that worked fine in my original P-90 Plato. I upgraded a couple months ago to a P-100 Triton. All of a sudden I got gcc failing on signal 11 while compiling the kernel. Turned off the the cache (internal or external) and it worked fine. Swapped the pipeline burst cache for async cache and it worked fine. Swapped my old 32M RAM (70ns) for 60ns EDO and it worked fine. It seems that there are many solutions to the same problem here. *note* The motherboard manual explicitly states that I need to use RAM *faster* than 70ns. Well, the RAM is upgraded and every- thing work fine now.
I can reproduce an occasional signal 11 with 'make -j zImage'. It is interesting to note that 9 out of 10 times it will fail with an "out of virtual memory" at the same place that the signal 11's occur. This is also where I can, 100% of the time, lock up my system using Gerard's NCR SCSI driver. There are no error messages when the lockups occur - no signal 11, no 'out of virtual memory', no indication of a problem whatsoever, just a solid HD light.
