+Issue #8: The AMDGPU driver is not loaded after installation
+======================================================================================
+
+When you are verifying the ROCm installation according to the :doc:`post-install instructions <../install/post-install>`,
+the ``rocm-smi`` and ``rocminfo`` commands might fail with the error message
+``Driver not initialized`` or not display any output. This could indicate
+the AMDGPU driver is not loaded.
+
+**Solution:** Ensure the AMDGPU driver is not on a denylist such as ``/etc/modprobe.d/blacklist-amdgpu.conf``.
+The location of this file might vary depending on the system distribution and version.
+To verify whether the driver is on a denylist, use the following command:
+
+.. code-block:: shell
+
+   grep amdgpu /etc/modprobe.d/*

+Issue #9: Cannot access the AMD GPU or accelerator after installation
+======================================================================================
+
+If the group permissions are not set properly during ROCm installation,
+you might get an error similar to ``Permission denied`` when attempting to access the AMD GPU.
+
+**Solution:** You must be part of the ``video`` and ``render`` groups to access the AMD GPU or accelerator.
+To learn how to add an account to these groups, see :ref:`group_permissions`.
