Excerpt from /var/log/messages.

On a Fedora 19 box, (guessing:) since the update to
google-chrome-stable-38.0.2125.101-1.i386, opening YouTube videos causes the
screen to go blank.  This also blanks all terminals ([Ctrl-Alt-F2] & Co.), so I
have to blindly log in and type "shutdown -r now" to reboot the machine.

When this occurs, /var/log/messages starts with:

| Oct  9 01:13:50 passepartout kernel: [  431.004031] [drm] stuck on render
ring

is required to analyze gpu hangs, so please always attach it.

(For the complete log cf. attachment.)

*After* the reboot /sys/class/drm/card0/error reads "no error state collected",
so if you need this file, please state so as then I'll have to set up a script
to copy it somewhere (because all the screens are blank so I can't do that
interactively).</pre>
