The CP tag failure has been fixed and will be included in any new release of Open Firmware.
It was indeed a bug. Instead of setting the CP tag in the embedded controller (EC), 128 bytes of invalid data was written instead. The EC just ignored the invalid data and behaved as if the CP tag wasn't there. The bug would only trigger if the EC had not been reprogrammed since power was applied. This is why ?sync-ec or deleting and adding the tag again would fix it. http://dev.laptop.org/ticket/12751 has the technical details. -- James Cameron http://quozl.linux.org.au/ _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
