Timer mode in OProfile 0.9.5 was broken (regression).  That was one of
the main reasons we put out 0.9.6 soon after.  Please do the following
to clean up your oprofile environment:

	opcontrol --deinit
	opcontrol --reset
	rm /root/.oprofile/daemonrc

Then uninstall oprofile 0.9.5 and download, build, and install 0.9.6.

Sorry for the inconvenience.
