In that case the frequency are set to 2.6 GHz for each coret instead of 80= 0 MHz for cpu0 and 2.601 GHz for cpu 1-3. =46urthermore I've the strong feeling, that the plugged in USB devices might have an effect. And in the mean while I would not even exclude th= e influence of the type of the 4 BOINC tasks (Asteorid@Home versus Einstein@Home / World Community Grid which I have to run with nice -19 in the back ground) at the bisect results. So all my ongoing attempts to bisect weren't successful till now. I just tested the latest git tree from today (v3.10-8615-g23e3a1d) - although f51e1eb is merged - the origin issue (cpu 1-3 set to 2.601 GHz after wakeup) is still here. --=20 MfG/Sincerely Toralf F=C3=B6rster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3
