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.

I was installing my video card earlier and I started getting the following error in the boot (I wasn't booting into GUI), "warning CPU frequency 3066590, cpufreq assumed 1599960" then after a minute or two the numbers would reverse but with the same error.
Other issue is that my computer is getting incredibly laggy lately, sometimes to the point of a 3-5 minute pause and sometimes complete freeze. It will boot up fine and usually after I start running a couple programs things will start slowing down....it seems almost random though. Sometimes I'll leave my computer on for hours and everything seems to work fine the entire time. Dell has told that it might be a Hard Drive issue so they sent me another one but I doubt that is the issue. Anyone know what might be causing this? Oh yeah...and I'm not running enough to really slow down my machine, a couple documents, chat window and internet window maybe, nothing major...sometimes e-mail client (Evolution)...thanks for any advice
Distribution: RedHat (RHEL, FC, CentOS), openSuSE, Mac OS X
you got smp enabled in your kernel?
Ahh ... DELL ... check if your system actually has HT enabled, they shipped a few models with dodgy BIOS's which didn't know they were HT capable, odds are you need to flash it and then enabled it. (DELL provides tools to flash during startup, so you don't need to fark arround with Windows).
Get yourself a process monitor, such as GKrellm, that will show you if your CPU is chewing loads of if your transfering data etc. the console based top command can also give you clues (kpm in kde does something similar, but you need to select what to sort by)..
It could be a hard drive issue actually, but i wonder, what size is your swap file? and have you got hdparm configured? (hdparm allows you to optimize (generally meaning "accellerate") the access speed for you IDE devices (so CD/DVD also).
Lastly, i take it you are running FC3, but what version kernel is that? and is it the vanilla one or a self modified/built one?
Half of the stuff that was said went right over my head. I am pretty sure my HT is working fine because in Windows it showed up fine. I have a gig for SWAP...I also have the newest kernel updated from yum. Other than that I'm not sure what the other stuff is....I'll have a new HD in by tomorrow and hopefully that will solve the issue...if not then I'm not sure what I'll do.
I'm also having an issue with my net, goes in and out of service (I'm on a university campus with a T1 line) but I am the only one that really experiences the problem to the extent that I have it (about every 20 minutes).
I think what chakkerz is referring to is whether or not DMA is on on your harddrive. If it is not on, processes which access the harddrive alot will slow the entire system (sometimes to a freeze-like state). This is usually caused by not having your IDE chipset support built into the kernel. To check if DMA is on, in a console (as root):
