Andrej, The experimental utrace support for perfmon2 showed up in the 2.6.26 patch. So you need to get 2.6.26 + utrace patch + perfmon2 patch. As for CONFIG_UTRACE, I was referring to the fact that the perfmon2 code automatically enables its utrace support if it sees CONFIG_UTRACE defined at compile time.
