display watermark is too large(92/63), disabling

[Chris]

Now I'm more confused than ever about these 'lockups' I've been
experiencing. The system has 'hung' twice in two days almost exactly
36hrs apart. The first was at 07:18:55 on 19 Feb, the next was last
night at 19:16:40 on the 20th. I'm going by the times shown on the clock
which I have set to show seconds. I'd installed kernel
3.19.0-031900-generic #201502091451 SMP Mon Feb 9 14:52:52 UTC 2015
x86_64 x86_64 x86_64 GNU/Linux on the 18th at 5:34pm. What I'm seeing
now instead of the 'Hangcheck' error is noted here at pastebin:

I know I've asked this question before and one response is that it was
informational messages from the video driver. I don't remember seeing
these when I'm running the 3.13.0-45 kernel is this just particular to
the 3.19 kernel? Is there possibly something with the video driver
causing the 'lockups'?

The output of dpkg -l | grep xorg | intel:

dpkg -l | grep xorg | grep intel
ii  xserver-xorg-video-intel
2:2.99.910-0ubuntu1.4 amd64 
X.Org X server -- Intel i8xx, i9xx display driver
