I'm not exactly sure what's wrong with the buffer - whether it's a case of not being able to access it properly or somehing buggy in the EFI code for reading files. No fault occurs when reading into it, it just doesn't contain the correct data. Either way, I'm going to leave your patch as-is and just ensure I fix this before the merge window. I think it's a good idea to have whatever workaround we come up with documented via an entirely separate patch. -- 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 majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
