Hi Paul,

Thanks for the patch.  I actually maintain this file upstream.  I am
concerned about the error you are seeing, -95.  Is it possible you can
provide me a 'dmesg' log of your boot up.  I want to see what chipset the
perf subsystem thinks it found.

I may want to handle this error a little bit differently than the patch
you provided below.

Thanks,
Don
