Comment 26 for bug 1719545

@<email address hidden>: Hello. Now I have a theory as to what the problem might be.

The upstream fix is actually a change only to the 'cpupower' tool, not the kernel itself. This tool is not part of the linux-image or linux-modules .deb files. It is built as part of the linux-tools .deb, which for some reason, wasn't included in the test build that I prepared for you.

I've updated the above link by adding the file: linux-tools-4.15.0-46_4.15.0-46.49~k1_ppc64el.deb

This .deb includes the updated cpupower binary. The full path after installation should be: /usr/lib/linux-tools-4.15.0-46/cpupower

Please install that .deb and use the included 'cpupower' binary when testing.
Thank you.
