Can you please apply the patch available at
http://cgit.freedesktop.org/~danvet/drm/patch/?id=0b3ecfa8c9b00f50d514fbcc12e34882b0fa695a
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
