Re: [Powertop] Strange Behavior - PowerTOP 2.0 Seg Fault

hm, that's something. seems like enumerate_cpus(); failed because perf_bundle was NULL in cpu by the time of perf_events->start(); call, but it did not crashed on any of enumerate_cpus() 332 perf_events = new perf_power_bundle(); 333 334 if (!perf_events->add_event("power:cpu_idle")){ 335 perf_events->add_event("power:power_start"); 336 perf_events->add_event("power:power_end"); 337 } 338 if (!perf_events->add_event("power:cpu_frequency")) 339 perf_events->add_event("power:power_frequency"); so it leaves only one suspect: enumerate_cpus() 269 file.open("/proc/cpuinfo", ios::in); 270 271 if (!file) 272 return; is that happeninig all the time? a *very* stupid question - do you have /proc/cpuinfo file?
