@Richard. you mean the firmware files ? i did install those files, manually, yes. But i have no idea which "manager tool" you could be referring to. Concerning "the official intel graphics driver": i am using xf86-video-intel with sna , like almost everyone here is probably doing. i tried sna, uxa xaa, also disabling dri or used ilo for dri. ubuntu(mint) is not my main system, i just have an old linux mint system on a partition i don't use anymore but that has exactly the same kernel problems. i am running gentoo linux. i tried the intel video driver and modules with nearly all the options (xorg config file, kernel module options for i915 etc) on mint and on gentoo, and i can almost certainly say that the system freezes have nothing to do with it. anyway, i am running now kernel 4.4.0-rc6 with extra cmdline parameter "intel_idle.max_cstate=1" and all seems to be good. it is the 3rd day now without freezing i believe. Thank you for your explanation with the cstate. yes, it is a limitation but i still prefer running the newer kernel with lower performance than having the old 4.1 kernel
