Bug 264305

Created attachment 234281 [details]

Happen at least on 5750G, fresh 13.1 amd64, drm510-kmod.
On second boot after power on - no panic.


I suppose that this = NULL:
rirb_base = (struct hdac_rirb *)sc->rirb_dma.dma_vaddr;

and it fail on:
		rirb = &rirb_base[sc->rirb_rp];
		resp = le32toh(rirb->response);
