Hi, which mesa version are you using? Thank you. The problem seems to have gone away on its own, with regular kernel updates. Mesa is the Debian unstable packaged version: libegl-mesa0:amd64 17.3.6-1 |

Created attachment 137012 [details] copy of /sys/class/drm/card0/error I'm running the top-of-tree Linux kernel; revision 1f07476ec143bbed7bf0b641749783b1094b4c4f The X server randomly hangs; I can't work out what triggers the problem. I'm not doing anything graphics intensive --- just emacs and xterms. This can happen anywhere from a few minutes after boot to after several hours; but I haven't had a full day's work without a hang for a couple of weeks. The bug is in a Dell laptop, that uses vga_switcheroo to swap between the i915 and an AMD R9 M295X. dmesg output: GPU HANG: ecode 9:0:0x85dffffb, in Xorg [2752], reason: Hang on rcs0, action: reset [ 1798.822701] [drm] GPU hangs can indicate a bug anywhere in the entire gfx sta ck, including userspace.
