hi ingo & others, it seems, that with 2.6.33, the perf report cannot correctly decode symbols from user-space objects: # Samples: 211435499487 # # Overhead Command Shared Object Symbol # ........ ....... ................. ...... # 99.78% :16956 378283e010 0x000000378283e010 ! [.] 0x0000378283e010 perf top decodes the specific shared object correctly. is this a known issue? i'm experiencing this on an x86-64 nehalem machine. thanks, tim -- tim@klingt.org http://tim.klingt.org Who need fossil fuel when the sun ain't goin' nowhere Amiri Baraka
