[BUG] powerpc: perf record crash

2012-05-10 Thread Sukadev Bhattiprolu
I get this crash when I run on 3.4.0-rc5 on a P6. ./perf record -a -d -- ./perf bench sched all I rebuilt 'perf' locally after building the kernel 3.4.0-rc5. Sometimes it occurs on the first attempt, sometimes on the second. Pls let me know if I can provide any other debug info.
