Kernel log traces
Reporter, is this still seen? No with 4.8.0. Indeed 4.6 suffered that bug of missing the GT interrupt of Braswell. |

Created attachment 124677 [details] /sys/class/drm/card0/error Hi, I am experiencing very frequent GPU hangs shortly after loging into X (a matter of couple of minutes more or less). Usually this leaves the machine frozen and in many cases it doesn't respond to a change to console even in a minute or two (in some cases it does move to the console after insisting some time). I'm running Debian GNU/Linux stretch (testing) with linux 4.6.0 on AMD64. The problem seems to be directly related to the 4.6.0 kernel as I don't experience it with 4.5.0-2. The box is an Intel NUC5CPYH. On the console the following message appears: [ 613.867307] [drm:intel_check_cpu_fifo_underruns [i915]] *ERROR* pipe C underrun Please find attached gzipped /sys/class/drm/card0/error as indicated in kernel log traces. The following are the kernel log traces: Jun 23 11:06:05 tierra kernel: [ 547.569175] [drm] stuck on blitter ring Jun 23 11:06:05 tierra kernel: [ 547.575354] [drm] GPU HANG: ecode 8:1:0xfffffffe, in Xorg [781], reason: Ring hung, action: reset Jun 23 11:06:05 tierra kernel: [ 547.575358] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
