Created attachment 124487 [details] /sys/class/drm/card0/error Hardware: Zotac ZBOX CI323 Nano User visible symptoms: After boot up and graphical log in, I can work for about half a minute, and then the screen freezes. Switching to text mode with Ctrl+Alt+F2 is possible, but it takes a very long time until the screen actually shows the text mode. (Maybe one or two minutes.) In text mode things are fluent again. Switching back to the logged in session, it's still hanging. This bug is reproducable on this machine and makes graphical log in infeasible. Software: Antergos Linux (Arch-based, rolling release). Ran into the bug for the first time on 2016-06-10, so the corresponding software update probably came in roughly in that week. (Not using the machine every day.)
