[scott]

I'm new to the list and would like to say hello to everyone. Now on to 
the meat.

I have tried to compile a kernel with a grsec patch 5 times now using a
couple of different methods and I keep getting a "No init found" and
"Couldn't support optional features" errors every time at bootup.
I'm trying to use a vanilla 2.6.32.27 kernel on 10.04 Ubuntu and it 
compiles fine,
just will not boot.

I've tried "CONCURRENCY_LEVEL=`getconf _NPROCESSORS_ONLN` fakeroot make-kpkg
--initrd --append-to-version=-custom kernel_image kernel_headers",
"CONCURRENCY_LEVEL=3 make-kpkg --initrd --append-to-version=-586
kernel_image kernel_headers modules_image".

I have all the reqs for building kernels such as build-essentials, fakeroot,
kernel-package, kernel-wedge, nurces-dev and qt for xconfig.

These are the steps I've taken. DL the kernel image from kernels.org, get
the patch from grsec.net, untar the kernel, cd into the directory created,
do a 'cp /boot/config-`uname -r` .config', 'make oldconfig', apply the
patch, then either 'make menuconfig' or 'make xconfig'. Then I do a
'make-kpkg clean' and run one of the commands in the first paragraph above.

I get the debs built and can install them just fine, but I keep getting the
same errors. I've cut out as many "Experimental" options I thought might
cause a problem and still get a kernel panic at boot.

Anyone have a clue what I'm doing wrong?

My first question is: did the patching go successfully? were you
applying the correct grsec version against a matching vanilla kernel
version?

And last, maybe you can attach your kernel .config content...and one
of fine people here will try to decipher what's wrong with it :)

The patch was matched and was successful. It compiled with no errors. 
Just the 'no init' at boot.
I'll post my .config later today as it's late here and have to work. I'm 
beginning to think it may have something to do with the limits on file 
size as I got a few warnings about out-of-range sizes. I have it set to 
1024.

Thanks for your reply,

Thanks for your reply.

  you are clearly using ubuntu, so here's a simpler recipe i've used
successfully.

  1) configure and build your kernel from the source
  2) "sudo make modules_install"
  3) "sudo make install"
  4) "sudo update-initramfs -c -k <kernel version goes here>"
  5) "sudo update-grub"

the drawback to the above is that your kernel is not built as an
official *package* but for testing purposes, it should do.  you'll get
your kernel installed under /boot, your modules installed, a new
initramfs image, and your grub file updated.  can you try it this way
and see if it makes a difference?

Greetings,After reading Linux Kernel in a Nutshell (by the way, great book), I now have my own kernel configured for my hardware needs.?
However, I have some really strange behavior. On tty1, the same tty that launches X11, I have to press twice each keyboard key.?Anyone has any idea what's going on? I am using a customized Debian Squeeze + OpenBox.
Thanks in advance, and thanks Greg for writing the book.
Ezequiel.

Hi Ezequiel

I'm new on this list as well but I don't think anyone will be able to
help you with the limited info that you have provided.
When you say you have a kernel configured for your hardware, did you:

A) Download the kernel from http://www.kernel.org/ ? In that case you
need to tell us which version you're using.
B) Get the kernel from git a git tree http://git.kernel.org/? We still
need to know exactly which version
C) Recompile your debian kernel? (2.6.32?)

If this bug is present with only a change in kernel config, it would
be interesting to see the difference between the working and broken
config.

I hope that helps,
Pico
