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.

This started randomly, I had not done any upgrades or changes. I have since tried reloading slackware from disk with no change. Lilo would not write to the mbr at the end of setup. sda1 is the root partition, sda2 is /usr, sda3 is the swap, and sda4 is /home. I'm out of ideas at this point and looking for some help.
trying to boot from a usb disk with /dev/sda1 as root produces the same panic. I formated that partition when I when through the reinstall process and ran a check at the same time so I don't think there is a physical problem with the disk.
I experienced a similar problem about a year ago with my tower PC, except that I was still able to boot from USB drives. What had happened in my case was that the motherboard's SATA controller had gotten confused owing to a faulty cable connection on one of the drives and, even after fixing the cabling, would not properly access the root drive.
Yes, I know that such problems should not theoretically happen, or at least should be recoverable by resetting the BIOS to its defaults; however, resetting the BIOS didn't fix things. Fortunately, I was able to remedy the problem by re-flashing the BIOS (booting the BIOS updater from a USB-connected DVD).
I only mention this as a last resort possibility to consider if all else fails (and assuming you have a means of re-flashing the BIOS).
I ran systemrescuecd and gparted did not recognize any filesystem on sda1 even though I reformatted it during the reinstall. I used gparted to set it back to ext4. I'm going to try the reinstall again.
