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.

None of the commands that would lead to a reboot are successful (e.g., reboot, shutdown -r now, init 6, etc.) The machine hangs after issuing "rebooting system." The keyboard lights flash as if the box were going to bounce but it just never follows through. Could APIC/ACPI have anything to do with it (see below)?
Any help is greatly appreciated!

I've already tried that one with no success. Does the APIC service/daemon have anything to do with this? (I guess it is pretty apparent I have essentially no idea what APIC/ACPI is. Can anyone enlighten me?)
I really appreciate all of the suggestions. All of my efforts have been in vain, though. I would really like to learn something from this experience anyway: what is APIC/ACIP? Why might one or the other cause this problem? Why might one imagine that disabling one or the other would help?
I am having the same problem, although my servers are FC3. The only way I can reboot is by connecting a PS/2 keyboard to the servers. Does any one has additional suggestions on how to troubleshoot this issue?
