Created attachment 130115 [details] error I have been bearing this issue for a few months already. My two monitors system would randomly freeze up, mainly forcing a hard reset to resolve, though there are a few times it would recover by itself after freezing for 20 seconds. During a freeze, the display would turn black for most of the time. Sometimes, it would just log me out. It can take place as soon as 30 seconds from logging in. I tried out LiveCD of (dev) Tails 2.11, Ubuntu 17.04 and I am able to use the system for the whole day without freezing up.

That is a good sign -- likely that the bug is fixed in a newer Mesa or kernel. Can you update your system to the versions on the LiveCD and see if it resolves the problem? Also, you haven't told us what Mesa version you have. That's very important.

Anyone looking into this bug? I am on Ubuntu 17.04 and the GPU hangs a few times everyday.

It looks like your xorg-video-intel version preceeds a fix that Chris Wilson made which resolved many gpu hangs: 4acd4a7d3d2f41227022fa7581cfb85a0b124eae Author: Chris Wilson <chris@chris-wilson.co.uk> sna/gen9: Emit a dummy primitive between VertexElements I would see if modesetting driver fixes your issue. Alternatively, you could build a newer sna and see if that helps.
