*** This bug has been marked as a duplicate of bug 89360 *** The description of the bug of which this one is supposed to be a duplicate, does not sound very similar - in case of this bug the system does not crash or freeze entirely. It freezes for a moment until the GPU is being reset. Maybe it has the same cause though, I don't know. I assume you know why you set it as a duplicate. One thing I noticed is that OpenGL applications do no longer work after that bug and the GPU is being reset fairly often afterwards until I restart the machine. Your bug relates to an invalid PTE either detected by DMAR or caused by it. Symptoms may vary wildly, but ultimately until the DMAR issue is resolved you will not whether you have any other genuine bug because of DMAR underpinning everything. |

Created attachment 118975 [details] /sys/class/drm/card0/error output I am occasionally experiencing GPU hangs on my computer. The configuration is a PC with an Intel i5-5675C (non-overclocked) running Gentoo Linux with a 4.2.3 kernel. The hangs seem to occur randomly, sometimes when running an OpenGL game, sometimes when just sitting at the desktop idleing. This causes the desktop to freeze for a few seconds. After the GPU has been reset, it is back to normal. dmesg output: [147443.830208] DMAR: DRHD: handling fault status reg 3 [147443.830213] DMAR: DMAR:[DMA Read] Request device [00:02.0] fault addr 21f9e000 DMAR:[fault reason 05] PTE Write access is not set [147443.830219] DMAR: DRHD: handling fault status reg 3 [147443.830221] DMAR: DMAR:[DMA Read] Request device [00:02.0] fault addr 21fad000 DMAR:[fault reason 05] PTE Write access is not set [147443.830399] DMAR: DRHD: handling fault status reg 3 [147443.830401] DMAR: DMAR:[DMA Write] Request device [00:02.0] fault addr 21f9e000 DMAR:[fault reason 23] Unknown [147449.741936] [drm] stuck on render ring [147449.742725] [drm] GPU HANG: ecode 8:0:0x85dffffb, in X [5694], reason: Ring hung, action: reset [147449.742726] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
