I have hit this before, in my case the driver pointer was null. It faulted on dma_ops->map_page which had nothing to do with the real problem which was the null driver pointer. I spent a long time looking at this until I figured out that the reported error was bogus compared to the actual problem. > > rg > kd > > _______________________________________________ > Linuxppc-dev mailing list > Linuxppc-dev@lists.ozlabs.org > https://lists.ozlabs.org/listinfo/linuxppc-dev > -- Jon Smirl jonsm...@gmail.com _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
