No, that would be papering over the real problem. All oprofile does is trigger perfmon interrupts (which act as some kind of NMI when soft-disabled but should be masked by MSR:EE when hard disabled). So there's a deeper issue here that we need to understand before we can propose a fix. IE. It should not have happened.
