Is this happening with libdrm 2.4.60? If so, that's a known
(user-side) issue and should be fixed by using any version but that
one.
What's the freedesktop bugzilla # for reference?

I believe it's this one
https://bugs.freedesktop.org/show_bug.cgi?id=89842#c19
Not really a world of choice on ubuntu to fix it though...
deckard@aineko:~/Development/projectara$ apt-show-versions libdrm2
libdrm2:amd64/trusty-updates 2.4.60-2~ubuntu14.04.1 uptodate
libdrm2:i386/trusty-updates 2.4.60-2~ubuntu14.04.1 uptodate
:(
That's unfortunate. I know next to nothing about debian/ubuntu or how
they do versions or how to even build packages for them. But they're
big distros, presumably they have support teams of some sort, perhaps
they can help you.
Assuming that switching away does resolve the issue for you, perhaps
you can also recommend that they avoid shipping that version, or
include this nouveau fix in it:
http://cgit.freedesktop.org/mesa/drm/commit/?id=812e8fe6ce46d733c30207ee26c788c61f546294
Fwiw debian has been tracking this as #789759, and they are shipping
2.4.62 which includes the fix.
Unfortunately the LTS version of Ubuntu (trusty) was updated to 2.4.60
several days ago without this fix.
I repackaged libdrm 2.4.60 with only the bug fix above and confirm the
patch above fixes the observed behavior in freedesktop bug# 89842/
debian bug# 789759.
I pushed the repackage to Launchpad PPA @ ppa:phurley/libdrm
Hopefully the Debian maintainer grabs this fix and updates the official
distribution version soon.

Yep.
Dropping down to 2.4.56-1~ubuntu2 definitely removes the
