> Are you sure this is not coming from a software you are using? For every problem I had / have with Intel GPU I can find other users on any distribution's bug tracker with exactly the very same errors in the kernel log, so I'm pretty sure I'm not the only one suffering from Intel GPUs. In fact I am surprised by the small number of people here with that problem.
But it's true there are some programs that are very prone to hang the GPU when used, like Chrome, Chromium, Firefox, Google Earth, KDE's taskbar, Virtualbox... all of them use some kind of 3D acceleration
