Xorg freeze when starting chromium-browser

[Richard]

I get messages like the following in the journal:

kernel: nouveau 0000:0a:00.0: fifo: CACHE_ERROR - ch 7 [chromium-browse[6657]] subc 3 mthd 15ec data 00000000

I can still SSH in.

Chromium Version 53.0.2785.143 Built on Ubuntu , running on Ubuntu 16.10 (64-bit)

lsb_release -rd:

  Description: Ubuntu 16.10
  Release: 16.10

apt-cache policy xserver-xorg-video-nouveau:

What you expected to happen:

  Chrome Browser window to open.

What happened instead:

  Outline of Chrome Browser window appeared and then Xorg froze. Mouse point could be moved on one display but between displays. Nothing was responsive on the UI.

Running Chromium with:

    chromium-browser -gpu

works and does not freeze.
