question about logging kernel problems when kernel blows up

[Scott Berry]

Hi there,

I have a friend who is trying to help me debug a kernel problem.  I am
wondering if there is any way to log the problems that the kernel
encounters when you load it and it blows up.  He needs this to help me
debug what is wrong.  Thanks for the help.

Hi Scott,

By default, you can check the dmesg output by entering 'dmesg' on the
console. This will show the boot process. You can also write the output to a
file (since it's too much information for 1 screen) using 'dmesg > file'.

Also, look in /var/log/messages.

By the way, what problem do you have with your kernel?

Nick

Well it wasn't wanting to mount the root system.  I have a friend trying
to get a look at it and see if we can get it going.  He is more
experienced then I am at kernels.On Mon, 26 Jan 2004, Nick Van Vlaenderen

Maybe the problem is in your /etc/fstab ? Or the root partition isn't
properly defined in your boot loader?

[Jude DaShiell]

look for /var/adm/messages or /var/log/messages the log you're looking for
will be found in that file.
