GPU error state

This may be a duplicate, not sure.

I have a Lenovo T520 that's docked with an external monitor connected via Displayport. Also have an additional screen connected via a plugable USB display adapter (assuming that's not related).

No idea how to reproduce, but the frequency seems to be increasing of late.

System environment:
-- chipset: i915
-- system architecture: 64-bit
-- xf86-video-intel: xorg-x11-drv-intel-2.21.15-7.fc20.x86_64
-- xserver: xorg-x11-server 1.14.4-11.fc20
-- mesa: mesa-dri-drivers-10.1.5-1.20140607.fc20.x86_64
-- libdrm: libdrm-2.4.54-1.fc20.x86_64
-- kernel: 3.15.10-201.fc20.x86_64
-- Linux distribution: Fedora 20
-- Machine or mobo model: Lenovo T520
-- Display connector: Displayport

As for the segfault, don't use UXA.

For what it's worth, I tried switching to SNA, but that didn't allow me to use my third screen over USB (at least it wasn't autodetected). I doubt this is the appropriate place to troubleshoot this, but perhaps that's why UXA is still the default in Fedora.
