Did you install the modules after you compiled the = kernel?
Did you run "depmod -a <kernelversion>" ?

yes I have done it and still the same probl= em.

You can't modules from a different kernel versi= on!!!

I understand that. Just want to check what = additional problems arise.

Looks like you didn't install the modules from = the new kernel.

I have installed modules via= "make modules_install" and depmod as well.

XCP default kernel is 2.6.27. You're trying to = use 2.6.32.
There might have been changes between the kernel versions.

If ide-disk module is not used/required anymore in = 2.6.32, then you should
remove it from /etc/modprobe.conf so that mkinitrd doesn't try to inclu= de it!

(replace it with the proper new module name).

"Invalid module format" means it's fr= om a different kernel and cannot be

Install for example Fedora 12, or any other distro = that has 2.6.32 kernel
as a default, and check which modules are used for your hardware,
then replace "ide-disk" in modprobe.conf with the actual module.<= br>

Will look into it.

Thanks
