          Priority: medium
            Bug ID: 81690
          Assignee: dri-devel@lists.freedesktop.org
           Summary: nouveau GPU locks up under memory pressure
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: hramrach@gmail.com
               URL: http://download.wakfu.asia/full/unix/
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: DRM/other
           Product: DRI

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.

[Wakfu[2016]]

an easy way to trigger the issue is to 

download the above game client, 
unpack, 
run the launcher script (wakfu/wakfu), 
wait for updates to finish, 
and press the PLAY button repeatedly until memory runs out. 

The client takes about 1.2GB
