I have been following these threads. Recall that I was involved, over a period of months, in the original "powernightmare" stuff. I have revived my tests (and wish I had left myself better notes), and am establishing a baseline before adding and trying this patch. My baseline is actually two tests with and without the previous two patches (the ones that were just sent a couple of days ago in "More power management updates for v4.19-rc1". I might have those results in some presentable form by later today (it looks O.K.) Results with this patch will take another couple of days.
