Hello! Me and kyak are spend some time to get kexec working on NN some time ago (about 2.6.35 kernel). Main problem was kernel cmdline. Some desync was found between kernel sources and kexec-tools. So cmdline was not passed to kernel. Not sure anybody tried it after again with more recent kernel. Don't forget to pass 'mem=32M' to kexec'ed kernel. This fixes error about some memory regions. -- Yury Bushmelev _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
