Can you make sure that C-states are not used on your system by checking 'sysctl dev.cpu | grep cx_usage' and 'sysctl -a | grep cx_lowest'? Timer code was not changing for quite some time already, while C-states were enabled by default less time ago, IIRC. -- You are receiving this mail because: You are the assignee for the bug.
