How to force a panic on CX/UX


At the system console type "<return>~i" or hit the console wakeup
button on the system.

        $
        $~iCPU 0 trap511 halt executed
        0001f37c [0001f37c] _halt+4      % f400c001 jmp      r1
        #0>

This takes you to console mode.  The number in the prompt is the
cpu you are currently running on.  Type "wb %pc ff".

        #0>wb %pc ff

This puts an ff at the byte location of the program counter (pc).
Type "r" and hit return. The kernel will panic will invalid
instruction.

        #0>r
        System trap (invalid instruction fault), pc = 1f37c
        panic:  trap

        Dumping to dev 601

        ...

While the system reboots you should see savecore message.  This indicates
that the panic succeeded and you will get a crashfile.
