When rebuilding kernels, make a backup of the last one that worked, and include a stanza in your /etc/lilo.conf to allow booting the working kernel. For example, with kernels found in /boot/vmlinuz and last known working kernel in /boot/vmlinuz.works, /etc/lilo.conf might look like:
boot=/dev/hda<\n> install=/boot/boot.b map=/boot/map vga=normal timeout=200 prompt read-only image=/boot/vmlinuz root=/dev/hda1 label=Linux read-only password=Vogons restricted image=/boot/vmlinuz.works root=/dev/hda1 label=Itworks read-only password=Vogons restricted
this will present a LILO prompt and wait 20 seconds for instructions as to which kernel to boot. The user may type
Itworksto select most recent build or most recent known good kernel. The “password” and “restricted” parameters prevent entry of additional boot parameters which might compromise security, without entry of the correct password. Make /etc/lilo.conf read/write to root, no permission to group or other.
Once a kernel is known to work, as root:
cp /boot/vmlinuz /boot/vmlinuz.works<\n> lilo
If you are using Linux and your system keeps crashing suspect the hardware, unless you are running some bleeding edge development kernel.
First, check the memory. There is a great program for memory check called memtest86 (http://reality.sgi.com/cbrady_denver/memtest86/).
The memtest program is an x86 boot sector. You can put it on a floppy and boot the suspect computer to memtest from a floppy drive. Or, my favorite is to load memtest from lilo as an operating system. Use an image clause in your lilo.conf file like this:
image=/vmlinuz #Your Linux kernel<\n> label=Linux read-only image=/memtest #Your copy of memtest label=Memtest
Sometimes CPU's just don't perform well at their rated speeds. You run into weird things like segmentation faults while using ls! Under clock your CPU. A good way to give your CPU a test is to run setiathome on your machine. See: http://setiathome.ssl.berkeley.edu/. This puts your CPU to work doing lots of fast Fourier transforms. Don't forget to join the Linux Journal setiathome group.
Still having problems? Lower the motherboard bus speed by a hair. If you see or smell smoke, shut off the power.
It happens often: an author sends a file created in DOS, which adds ^M throughout the text. To globally remove all ^Ms from a DOS file I use one of the following two options:
dos2unix <filename> bni:or
The ^M is produced by typing CTRL-V, then CTRL-M. Use them both—for a bit of variety!
“Linux happened without the help of deep pockets—how can we keep the magic?”
—Bruce Pehrens, posing a question to Michael Dell at LinuxWorld.
“Linux has to change the world more than the world needs to change Linux. Because IT sucks.”
