I don't think it's a fix per se, but rather a new config option: it used to be that I turned on compilation with "-g" unconditionally (sorry, but I hate not having debug info around when you need it...). Now Sam (finally! ;-) added a CONFIG_DEBUG_KERNEL option, so if you didn't turn this on, the kernel will be compiled without debug option and the resulting object files will be a lot smaller. BTW: someone really ought to look into why the debug info is so big and what could be done to handle it more sanely. For example, we get tons of debug-info replication due to header-files etc. It's rather embarrassing how low the state of the art is w.r.t. debug info management... --david
