Something like a shell would do) and interact ? I don't think you can actually stop the kernel. The linux kernel is multi-threads and events driven, so I doubt you can stop and restart it that easily. BUT if you want to interract with userland, you can implement a syscall on your own, or create a proc device (for instance) to let user read / write data to the kernel. For instance, you could create a proc entry called gettime, and when user reads it (ie: cat /proc/gettime) you would provide a proper answer. Hope this help.
