Yes, I rebuilt all modules which come from ports after upgrading to 12.2

        NOTE:   your OpenCL library declares to support OpenCL 2.2,
                but it seems to support up to OpenCL 1.0 only.
        NOTE:   your OpenCL library only supports OpenCL 1.0,
                but some installed platforms support OpenCL 1.1.
                Programs using 1.1 features may crash
                or behave unexpectedly
