<pre>On BSW, it's probably better to do testing of this kind of issues also with
ACPI ondemand governor, in case issue is related to process scheduler / power
management.
Please test performance of the problematic commit and commit preceeding it
after booting kernel with following kernel bootup option:
"intel_pstate=disable". How large the BSW perf difference is with that
configuration?</pre>
