Full core dump

I found this on the logs, I honestly don't know what the error could be.

EIR stuck: 0x00000010, masking

It happened while loading a VM in gnome-boxes. Besides some glitches in the VM,
no visual artifact was noticed, in particular no glitch in the outer desktop
(the VM was not fullscreen).

The VM is a Fedora Rawhide, using the qxl driver (in case it matters).
gnome-boxes was built from jhbuild, using mesa
7577cdd8300068bdf1eda426951d7141450283aa (+ my DRM-swrast patches, but they are
not in the rawhide VM and they don't touch GLX or the intel driver, so they
shouldn't matter here) and e8c3c1358ecaf4e90f7d43762357ae6f8e2022b6

The outer X was xorg-x11-server-Xorg-1.14.4-9.fc20.x86_64 (Fedora 20) +
xorg-x11-drv-intel-2.21.15-5.fc20.x86_64, with SNA enabled. Kernel is
3.14.6-200.fc20.x86_64.

This is a GM45 card.
