Description of problem: Cpuscaling fails ondemand test section only on RH6 x86


Version-Release number of selected component (if applicable):  RH6 x86 / v7-1-2-25



How reproducible: Every time


Steps to Reproduce:
1.  Install RH6 x86
2.  Install v7-1-2-25
3.  Execute cpuscaling
  
Actual results:  Userspace and performance pass.  Ondemand fails.  Failure only occurs in x86. x64 passes successfully.  


Expected results:  Ondemand should complete work at the same speed as userspace.  


Additional info:

We executed "watch -n1 /sys/devices/system/cpu/cpu*/cpufreq/cur_scale_feq" to watch the processor speeds as the test was executing. It showed the processors going to the same high speed during ondemand as it did during userspace, but for some reason ondemand took longer to execute the test task.

Gregg, do you still see the failures with the v7-1.3-19 beta?
