Hello, I'm experiencing a (I think) similar problem. When working in an Itanium2 Montvale machine (SuSE Enterprise 10 Service Pack 1, kernel 2.6.16.53-0.8_SFS2.3_0-default) with the supplied kernel and perfmon packages I can only make the "old_ia64_examples" work, but when I try to run the codes in the "examples" directory, I get errors like "pfm_create_context failed" and "Your kernel does not have performance monitoring support!". As far as I've seen, the problem is with the pfm_create_context function call.
Do you have any idea of how to fix it?
