Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

dnw is a download tool for ARM. Maybe secbulk is it's driver. I don't know much about it. Any help would be appreciated. Thanks!
I realize that the original post is over a year old but I am having the same problem with VirtualBox. dmesg: vboxdrv: module verification failed: signature and/or required key missing - tainting kernel
VirtualBox appears to function properly but I sure don't like this error. I've done a fair amount of searching to no avail. I suppose I will post a new message and see if I can get any decent fix suggestions.
