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 have successfully installed FC5 in my new home computer, but I can not update the kernel because it crashes in the boot process. I have posted a bug in Fedora's bugzilla but I understand that people there must be very busy and maybe be the problem is not so serious once I can run the kernel shipped with the CD's. But in my point of view this is serious enough to make me consider to change to other distro, since by now I can not even install special drives for my Radeon graphic card (OK it runs with vesa module, but, again...). I have also posted this in the Fedora forum but got no answers. Maybe someone can point for a place where I can dig more information and solve the problem. Here follows basic information about my configuration and a copy of the screen I got when try to boot from a regularly updated kernel (yum update...). This happened with versions 2.6.16-1.2096, 2.6.16-1.2111 and yesterday with 2.6.16-1.2122.
AMD 64 3000+
I am using a ASUS A8N-E motherboard with nvidia sata controller.
The RAID BIOS support is enabled
I am using LVM and hardware RAID 0 with 2 sata HDs
FC5 686 kernel version 2.6.15-1.2054
This is what I see in my screen when I try to reboot with the newly installed kernel:
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.16-1.2122_FC5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet

[Linux-initrd @ 0x37e3c000, 0x1b3698 bytes]
Uncompressing Linux... Ok, booting the kernel.

Kernel panic – not syncing: Attempted to kill init!
I have tried to create new initrd images explicitly loading dm and nvidia controller modules but it doesn't work.
So, any help will be welcome. Or maybe the best solution is to move to another distro wich doesn't have this kind of problem.
Thank you for the attention
I have it working now. Visit this link so you know your whereabouts and follow this procedure :
1)Download mdraid-rpm mentioned in bugzilla and install it
2)fix the raid size by typing “dmraid -a n && dmraid -a y”
3)remove kernel 2.6.16 (if installed)
4)install the kernel again (this generate a proper initrd)
5)reboot and be happy

I think that I have LVM support enabled because I am running FC5 kernel 2.6.15-1.2054 using LVM. Only when I update the kernel with yum (regular update) that I am not able to boot from the new kernel. So do you think that the update process is disabling that support only for the new kernel ? I have tried to create new initrd version asking explicitly to include dm and sata_nv modules to be included. But, I think there is something in this direction and the problem is related to the update process. Maybe there is another place where I can find some help but I dont know where.
Thank you, anyway
Maybe we've got some light here finally. I am sorry but I did not check udev's release notes. I did not even know I had to setup udev. Where are them ?? But it is my understanding that udev starts to run after the filesystems are mounted. Am I wrong ?? And why it works when I boot with the older kernel and not with the new one? Anyway I checked /etc/udev, here is the output :
Ok. I did read the instructions! But I still could not get what exactly I have to do since there already is an entry for device-mapper at /etc/udev/rules.d/50-udev.rules and fstab does list logical volumes. I tried to create initrd images files (with -v option) and I could observe that it is loading the appropriate modules (dm-* and sata_nv) in the initrd image. I can boot with them but, again, only the original version of the kernel (2.6.15-1.2054) goes well. Obviously I have tried to use the scroll-lock key, but it did not work very well. I can see messages of loading the dm-* and scsi and sata_nv modules when I am booting the old kernel but not when I am booting the new ones. I am saying that I can't see the messages and not that the modules are not loading (scroll-lock key). It is hard to understand why it happening because it runs very well with the 2.6.15 version. I can not believe that the newer kernels do not have this kind of support. Next thing I am considering to try is to generate the new version myself. I really think that is important to be able to update the kernel although the only problem I am having now is that I cannot load the ATI video driver. Maybe I should join some mailing list or look for help elsewhere. I am willing to accept suggestions. I think that it is something related to the initrd process. Is there a way to load a module trough an option in grub.conf ?
Is it possible that I am the only one having this kind of problem ? Raid and lvm are becoming very popular and I should expect to find many people using them. Any help is welcome.
Re the ATI driver -- Did you read the "sticky" note in the first line of the Fedora forum about ATI and nVidia drivers? Basically, the recommendation is to only use precompiled drivers from sites like livna.
You might find this thread interesting. It's talking about problems with the nVidia CK804 driver on AMD 64 processors. Further down in the thread there's a "patch" to the driver code proposed. (Having neither an AMD 64 system, nor a nVidia controller, I didn't read the whole thing. But a quick Google for nvidia and ck804 turned up lots of "problem' reports.)
Well, the thread code is a little deep for me. Is useful to know that there is somebody taking care of it. But I still dont understand why it only crashes with updated kernels. It makes me think that there is something wrong in the update process and Anaconda does the right thing at installation time. About the video drivers, my intention is to install them from livna. And I will have to do it since the official one doesnt have a good performance so watch dvds is painful.
Thanks for your attention.
I just was realizing that the problem is related to kernel version 2.6.16-* . Yesterday I installed a IDE disk im my machine. Then I installed FC5 (version 2.6.15-1.2054) and updated to the most recent kernel version. So now I have two VolumeGroups:
VolGroup00 : 2 Samsung s-ata 250G with RAID 0 enabled in the controller.
VolGroup01 : 1 IBM IDE 25 G
FC5 is installed in both disks and 2 kernel version in each (2.6.15-1.2054 and 2.6.16-1.2122). So now when it boots the 2.6.15.-1.2054 version, I have no problems it doesn't matter from wich disk I am booting. But when I use kernel version 2.6.16-1.2122 it issues the same error related to VolGroup00 and the only difference is that when I use IBM disk it boots anyway because it does not need anything from VolGroup00. I have debug option turned on in the grub.conf file and the error is the same :
device-mapper: dm-stripe: Target length not divisible by chunk size
I will try to post this bug in a kernel related mailing list.
Distribution: Gentoo (desktop), Arch linux (laptop)
Just an idea: If I were you, I would compile the kernel from source.
By compiling, I can control what option to be turn on or off and make it optimize for my computer.
You have a very strong CPU, compiling take you just a few minutes, why don't you try it
[snip]I will try to post this bug in a kernel related mailing list.
Just a thought: You might want to look at the nVidia site to see if they offer a Linux driver for your configuration. If it's like nVidia's video drivers, the Fedora policy forces Fedora to use non-proprietary versions (i.e., written from scratch, using whatever specifications nVidia has released) of the nVidia drivers rather than the binary drivers released by nVidia.
