Bug Description

System will hang immediately with 4.3 kernel above on SKL-H GT4 sdv.
The workaround for this is intel_idle.max_cstate=6/7 boot option.
But intel_idle.max_cstate=8 will generate system hang

Please integrate this patch into 16.04 kernel before kernel freeze although it have not entered into mainline kernel.

April 7 is kernel freeze. I'd like to see this patch make it into linux-next before I apply it.

XiongZhang (xiong-y-zhang) wrote :

Ubuntu 15.04 has SKL-H intel_idle driver support also, so we need to back port this patch into 15.04.

Sorry, it is 15.10 not 15.04.
