Is it fixable?

And what are x11perf -aa10text -aa24text -rgb10text -rgb24text results on GT2 ?

Btw couldn't compile your kernel:
  CC      drivers/gpu/drm/i915/i915_gem.o
drivers/gpu/drm/i915/i915_gem.c: In function ‘i915_gem_phys_pwrite’:
drivers/gpu/drm/i915/i915_gem.c:396:2: error: ‘ret’ undeclared (first use in
this function)
  ret = i915_gem_object_wait_rendering(obj, false);
  ^
drivers/gpu/drm/i915/i915_gem.c:396:2: note: each undeclared identifier is
reported only once for each function it appears in

DRM and i915 was set to built into kernel.
