Is the problem with "Perf" or the hardware part (i.e., "Hardware Performance Counters")? Can I revise the problem by simply modifying the code? How much work is needed? heya, might be some callchain processing bug, but I can't reproduce it on my setup.. would you have/make some simple example that would reproduce the issue? Another option is that you'd send perf.data together with 'perf archive' data. Also.. we support 2 dwarf unwinders (libunwind/libdw).. not sure which one you have compiled in, but would be helpful to see if the other shows the same. perf -vv + ldd `which perf` Output will help us find out which unwinder is being used, as well as the version of perf being used. - Arnaldo
