Of course it is. You find the module that isn't freeing it's resources, fix it, and you don't get the panic when you access /proc/ioports. It's really that simple. Thinking that modules shouldn't be able to kill the kernel isn't goint to help. Everything that runs inside the kernel has the necessary priviliges to destroy anything in the kernel. > not be able to kill the kernel -- apart from that, I can trigger the bug in > the very early "ash-system" that KNOPPIX provides.
