When there is memory pressure GPU tends to hang. This is probably related to system memory pressure (not vram) although I have no idea about vram utilisation. Usually crash happens when I start an application that uses the GPU and the system starts to swap and/or OOM killer kills something and/or applications crash due to bad handling of OOM condition. 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GeForce GT 620 [10de:0f01] (rev a1) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.

Maybe this is somewhat relevant. The PC has supposedly working IOMMU which might be reason for the page faults. I am not sure how the memory mapping for the GPU works.
I'm seeing something similar to this on a dual-socket Opteron system with kernel 4.2. It is sufficient for all memory to be exhausted on one NUMA node; when Linux attempts to recover by migrating processes to the other node this bug is triggered.

Hi guys, I have been receiving this error which appears to be the same error. It causes the system to completely hang, video completely frozen. The system log says it's related to Chromium, I had it happen to me twice within a half hour. I wasn't doing anything too intensive, mostly had Chromium open with Eclipse and Thunderbird. First, some info about my system: ~$ lsb_release -a LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch:core-4.1-amd64:core-4.1-noarch:security-4.0-amd64:security-4.0-noarch:security-4.1-amd64:security-4.1-noarch Distributor ID: Ubuntu Description: Ubuntu 15.04 Release: 15.04 Codename: vivid ~$ uname -a Linux kubuntu-cboyd 3.19.3-031903-generic #201503261036 SMP Thu Mar 26 14:37:55 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux ~$ lspci -v 06:00.0 VGA compatible controller: NVIDIA Corporation GF106 [GeForce GT 440] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Micro-Star International Co., Ltd.

Hello, do you have a test program that triggers this without much dependencies which you can upload? Comment #1 says something about uploading large texture array.
Created attachment 120413 [details] freeze log I'm getting similar issues after while. See my log file. lspci | grep VGA 01:00.0 VGA compatible controller: NVIDIA Corporation GF116 [GeForce GTX 550 Ti] (rev a1) Is it related?
I think I am also affected by this nouveau bug, on : 01:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 645 OEM] (rev a1) Now I have installed koops, I can provide more traces or data if anyone want to tell me what to do.
