fatal user trap:

    trap entry = 0x2 (memory management fault)
    a0         = 0x22016605c
    a1         = 0x1
    a2         = 0x0
    pc         = 0x120006a58
    ra         = 0x12000690c
    curproc    = 0xfffffc00043f4f88
        pid = 6351, comm = cpp

Does that tell me anything?

Hmm.  The RAM is certainly parity RAM.  How do I tweak clock speed on a PC164?
