I'm mucking my way around pretty well now. I noticed the drivers in the kernel directory have symbol files. When I build my driver, it is striped and no symbol file is gerneated. Is ther a trick to do this? Use 'make DEBUG=-g' when building the module. > Also, kgdb in the the 7.0 release doesn't seem to support add-kld... Is there an easy way to upgrade this? Just grab the kgdb sources from RELENG_7 and apply the to your 7.0 tree and build a new kgdb. It is also probably safe to just grab a kgdb binary from a newer 7.x snapshot directly. -- John Baldwin
