It happens also with more recent versions, such as any kernel ranging from 4.10.5 to very recent 4.17.10, latest mesa (18.1.5) and libdrm (2.4.93).

However, I think I have a different chipset, it is reported in Xorg logfile as "NVIDIA NVA5", while in the kernel dmesg as "NVIDIA GT216"...

It might be related to a similar crash reported in similar bug:

https://bugs.freedesktop.org/show_bug.cgi?id=70390#c24

The crash does not happen when the video is played directly with gstreamer (e.g. gst-play-1.0 from a terminal).

Maybe the following output is more meaningful (kernel 4.18):

At the moment, the only solution is to add the following line to /etc/X11/xorg.conf (under Section "Device"):

Option "NoAccel" "true"

because setting the kernel module option "noaccel=1" also leads to a crash due to some other silly bug !

There are no reports earlier than year 2013, so this bug has probably been introduced that year (and never fixed since then)...

I was wrong in my previous comment (Comment 7)...

I have now verified more carefully and realized that this bug has been around at least since kernel version 3.0 (August 2011) !

At this point, it might even be that this bug has existed since the initial release of the driver...
