Hello,

I patched the kernel and installed both libpfm and perfmon, however I got segmentation fault while I tried running command: "pfmon --help'. Could anyone help me to figure it out please?

I am running Ubuntu 9.04 on kernel 2.6.29. I downloaded the latest version of libpfm, perfmon, and the base system patch from the sourceforge page. My processor is Intel core i7 920 and I adjusted related configuration when I configured the kernel.  Following is the debug message from gdb:
