You should use hwpmc to verify where the application is really

pmc: Unknown Intel CPU.
module_register_init: MOD_LOAD (hwpmc, 0xffffffff8029906d,

OK, this is the famous problem with modern CPUs that jkoshy has
declined to work around :( There are patches for this in perforce, see
http://perforce.freebsd.org/changeView.cgi?CH=126189
I got hwpmc to compile (but only as module)
hwpmc: TSC/1/0x20<REA> P6/2/0x1ff<INT,USR,SYS,EDG,THR,REA,WRI,INV,QUA>
but when I try to use pmcstat I receive this error message:
pmcstat: ERROR: Initialization of the pmc(3) library failed: Device not
configured
kldstat lists hwpmc.ko as loaded and I have options HWPMC_HOOKS in my
kernel.
Any idea what's go wrong?
