We absolutely must get a more detailed answer before going any further. Simply put, if we're remapping the EFI regions into the virtual address space and calling SetVirtualAddressMap() on hibernate resume there is no reason that anyone should be using the old mappings. And since you've demonstrated that we *are* using the old mappings, we've likely got a bug somewhere that we need to get a handle on before we paper over the issue. Where exactly is the old mapping address being used? Is it that efi.systab->runtime->get_variable is incorrect? If you could paste the disassembled output where the page fault occurs, that would be helpful. -- Matt Fleming, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
