Subject: Kernel Panic 2.6.29.6 AMD Geode (in CS5536 IDE ?)

Hi,

I'm not on the mailing list, so please cc me. If needed I can provide
further information.

I am trying to build purpose built 2.6.29.2 kernel for my ALIX.2
[http://www.pcengines.ch/alix2d2.htm] instead of the generic all
modular 2.6.26 kernel in Debian.
The idea being is to have a slimmer kernel, no initrd*, and to include
ALIX specific features that the Debian kernel does not have.

(*support is enabled, but everything needed for boot should be built-in)

It is not my first kernel build, I tend to do this for all my
machines. Although it is the first time I have tried to build for this
system.

My build environment is as follows:
The host is a 64bit Debian (testing) MacBook pro. However I have a
100% 32bit Debian (stable) chroot install, which I also used for this.
I explicitly set ARCH=i386 otherwise my 64bit CPU is detected. This is
in effect a cross build, but not for an alien architecture and using
the normal host gcc.
(gcc (Debian 4.3.2-1.1) 4.3.2)

sudo chroot /blah
cd /usr/src/linux-source
make ARCH=i386 clean
make ARCH=i386 menuconfig
make-kpkg --us -uc --arch i386 binary-arch

scp, install the package and then boot.

(console seems to be repeated because it is given via grub and complied in)

Kernel panic - not syncing: Attempted to kill init!


I have tried to tweak the config some more since I captured that dump,
but they all die before reaching init as above.
I've attached my latest config, which still gives the same error but
is not the exact one for the dump above.

Would be grateful for help, advice or a patch. If you need anything
further from me please let me know.

My guess is this bug is due to 1 of 2 (obvious) bugs:

* An error/bug in the cs5536 module, or the one init-ed after it.

* A missing dependency declaration in the Kconfig file.

Regards

Thorben
