I'll keep the paragraph about MIPS and the example configuration though, as I think its important information to reproduce the problem, and to justify why it wouldn't be appropriate to just rename the files (which was my first reaction). > Reviewed-by: Frank Rowand <frowand.list@xxxxxxxxx> Thanks James
