Urgent pleeease help! stuck!

[Praseen Preman]

Hi guys,

I am currently stuck up with a few issues while inserting some rudimentary
modules into the linux kernel and recompiling and running it, there after.

I am currently using the Ubuntu Hardy Heron 8.04 LTS, kernel version
2.6.24-26. I wanted to insmod and modprobe a few of my own hand written
rudimentary modules into the kernel. I succeeded in my above venture,
but with a few unwanted side effects.

The kernel version 2.6.24-26 shipped with the Ubuntu Heron LTS was not
allowing me to insert a module compiled from the 2.6.24
kernel source tree.

So I recompiled the sources for the 2.6.24 kernel
sources and booted into it using grub.This time around I was successful in
inserting the kernel
modules, but *modprobe failed *though.

The issue I was facing was that, my nVidia drivers and
creative sound card drivers failed to work at first for the 2.6.24
version kernel and soon for the shipped 2.6.24-26 kernel too it failed
to work. Following this X windows too ceased to work properly for both
the kernels.

What  isthe best way to solve and avoid such a scenario.
I have a hunch that the since both the compiled 2.6.24 kernel and the
shipped 2.6.24-26 kernel used the same file system when they load ,the
2.6.24 kernel corrupted the udev configuration when it loaded and this
corrupted udev created problems for the 2.6.24-26 kernel when it loaded
too. Please let me know the right approach to such a scenario and how
to solve it.

Does creating seperate ext3 filesystems for the multiple versions of the
kernel
help solve this issue? What is the suggested system configuration for
kernel/ driver developers.

Thanks and Regards,
Praseen
