I looked into your kernel logs and there is only one interesting part: ~~~ кві 02 13:12:23 manjaro-pc kernel: i915 0000:00:02.0: GPU HANG: ecode 9:1:0xfffffffe, in UE4Editor [4360], hang on rcs0 кві 02 13:12:23 manjaro-pc kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. -- Reboot -- ~~~ However if you want to capture full crash log along with /sys/class/drm/card0/error it's not easy task - I used netconsole for it. You can contact me at <a href="mailto:andrzej1_1@o2.pl">andrzej1_1@o2.pl</a> and I will give you details how to do it.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
