I was able to track perf breakage down to this patch:

"Reapply upleveled PMU interrupt patch"

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-precise.git;a=commit;h=19297b769223795a7cd1082f041bb355c498961c

that tries to enable hw support instead of sw (as vanilla does).
Latest Linaro TILT doesn't carry it and acknowledged it was not ready for prime time.
