But as long as *any* user space is able to kill the kernel or shut devices off, requiring reloading modules, the issue isn't solved. Given that some people always rattle the cage of "remove module unloading", this issue _must_ be fixed. Requiring to reload a module is not a solution. -- Matthias Andree Encrypt your mail: my GnuPG key ID is 0x052E7D95 ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
