Hi Curtis,

What does "x/4i $pc" tell in gdb?

Could you also try to inspect 'dmesg' and paste the instruction inside < >, please?

I assumed you meant this.

It looks like the 'friz' instruction came in with PowerISA 2.03 or 2.04.  PPC970 conforms to 2.02 and/or the legacy PowerPC ISA, so does not have the 'friz' instruction.
Comment 4 Curtis Hamilton 2019-09-27 20:29:08 UTC
Seems the only fix is new hardware.  Therefore this is OBE.
