I don't think so. I'm using the following packages:
xorg-server-1.9.5 xf86-video-intel-2.15.0 libdrm-2.4.25 mesa-7.10.2
I quick google search suggests that at least some of them are too old to support SNA.
Can you please apply the patch available at

This one will let your gpu keep hanging in the "stuck on semphore wait" condition. Later on the hangcheck should kick in and grab a gpu error state (in the file i915_error_state in debugfs). Can you please attach that one?
Thanks, Daniel
