Created attachment 134628 [details] Output of /sys/class/drm/card0/error I updated Arch Linux' kernel to 4.13.3-1-ARCH and GUI was completely unusable. I would boot up the system, log in, launch i3wm, open Chromium and system would just hang. Nothing would work, not even magic SysRq keys. I am not sure that the issue is with Chromium, since I would open it up straight when I log in. Also, it doesn't matter what is open on it. Last time crashed just with one single "New Tab" - but it recovered (the only time it did recover, out of 4 boots). Crash occurs just couple minutes after launching i3wm. Crash does not occur in CLI. I have reverted to 4.12.13-1-ARCH, and crashing does not occur. Error log is attached.

I just took a look at other recent issues, and #102912 sounds very similar to my issue. (https://bugs.freedesktop.org/show_bug.cgi?id=102912) >If a second tty is opened before login, its possible to switch to tty2, than >the GPU resets until the next freeze. This would explain why GPU reset only on 4th boot - I had tty open >If no other tty is started, only power-off works, no reboot, no magic keys. Exactly. I also saw Elizabeth's comment, about #103034#c2, and I will try that out soon. (https://bugs.freedesktop.org/show_bug.cgi?id=103034#c2)
Yup, booting with intel_iommu=igfx_off seems to fix the issue. *** This bug has been marked as a duplicate of bug 103034 ***
