Hi Stephane,
I downloaded the new version of perfmon and the matching libpfm. I built everything on a p6 based machine. The kernel booted fine. I tried the task_smpl_user in the libpfm examples. That crashed the kernel. What was on the xterm:
$ ./task_smpl_user ls measuring at plm=0x8 programming 2 PMCS and 2 PMDS Segmentation fault
