Hi guys, This looks like the same problem the imx guys were seeing in:
https://bugs.launchpad.net/linaro-landing-team-freescale/+bug/893653 I'll mail Nico on linaro-dev about including the fix from mainline. Note that OMAP isn't providing PMU platform_device so perf isn't going to work with these fixes, you'll need to pick some more out of linux-next and off the list for that.
