"One button click pad" - I guess that explains why X only recognizes a
single button. The kernel mis-recognizes it. This is a regression, since
in the 6.x kernels it still works fine.
It is also nothing to do with DRMKMS, it also happens in the GENERIC
kernel. X uses the VESA driver there (which is sub-optimal since it uses
a resolution of 1024 x 768 instead of 1600 x 900).
The assertion failure I mentioned is in this fragment of code, for
reference, line 2833 of src/sys/external/bsd/drm2/dist/drm/i915/i915_gem.c:
2826 static void
2827 i915_gem_object_move_to_inactive(struct drm_i915_gem_object *obj)
2828 {
2829 struct drm_i915_private *dev_priv = obj->base.dev->dev_private;
2830 struct i915_address_space *vm;
2831 struct i915_vma *vma;
2832
2833 --> BUG_ON(obj->base.write_domain & ~I915_GEM_GPU_DOMAINS);
2834 BUG_ON(!obj->active);
2835
2836 list_for_each_entry(vm, &dev_priv->vm_list, global_link) {
2837 vma = i915_gem_obj_to_vma(obj, vm);
2838 if (vma && !list_empty(&vma->mm_list))
2839 list_move_tail(&vma->mm_list, &vm->inactive_list);
2840 }
