Right I somehow lost the TS_FLAG_INIDLE setting in tick_nohz_idle_enter(), which ruins the whole thing. You probably think I should have detected that with light testing and you're right. Not checking dmesg was a bit sloppy from my end... I'm fixing that and will send a v2 soonish. Thanks a lot for testing! -- Frederic Weisbecker SUSE Labs
