I'm just a lurker on the list at the moment but thought I could easily do this to help out. Log attached. A little feedback on the instructions - cpufreq-bench's Makefile doesn't have an install target although the instructions say to do make; make install, I copied the binary manually. Copying these results to the list as requested but is that really necessary for everyone? Could you summarise the results for us all when you've got enough please?
