I've dumped the actual content of 'range' and 'addr' at the failure point (i.e. ar point that returns error with e38c0a1f but passes without e38c0a1f ): OF: default map, cp=0, s=10000, da=70 range: 01 00 00 00 00 00 00 00 00 00 00 00 addr: 00 00 00 00 00 00 00 00 00 00 00 70 Nikita -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
