To get rid off these 2 errors:
[ 18.669068] i915: unknown parameter 'i915_enable_rc6' ignored
[ 18.669073] i915: unknown parameter 'i915_enable_fbc' ignored
Just remove the "i915_" prefix, it was removed in recent kernels. Maybe when those two options are used again you can get results similar to the ones before the upgrade.

I'll try to change to UXA acceleration, thanks!
