Sergey, can you please run the workload under turbostat on the base 6.1.y and on 6.1.y with the problematic commit reverted and send the turbostat output from both runs (note: turbostat needs to be run as root)?
Please find attached the turbostat logs for both cases.
The turbostat data suggests that power limit throttling is involved.
Why do you think so?
I observed sustained processor package powers over the PL1 limit of 6 watts, combined with increased busy % while at the same time power and CPU frequency going down. I admit the time constant of 28 seconds only seems to be exceeded once.
Since I seem to be unable to function without making a graph, some are attached, including Idle state usage, which might be useful for your other email. (The graphs are poorly labelled and such.)
