Wow, something is broken again (glxgears doenst work again). I checked twice (with two versions of agp)

Only new is that this error is being displayed:

error: [drm:pid1716:i915_mem_init_heap] *ERROR* called with no initialization



I checked modules from git(again), and they still works, new (actually old) lor is still there:
