LinuxQuestions.org - [SOLVED] Problem when using kernel module (built from sources)

Hi all !

I do encounter some problems when trying to re-use a kernel module i built from source.
The module is "e1000e", which is a network driver for Intel network card.
The setup is a brand new "Dell T1650".
The kernel is a

Code:

Linux epr-pi-10 2.6.18-194.el5PAE #1 SMP Tue Mar 16 22:00:21 EDT 2010 i686 i686 i386 GNU/Linux

used by a RHel55ES.

This computer (T1650) is not certified for RHEL55, and i can see that the e1000e module shipped with RHEL55ES is obsolete (ver 1.0.2-k3) , i then downloaded the version 2.1.4, and built it over the very same kernel using the informations given in the readme file.

My problem is that if i try to reuse this newly built kernel module i got some error, as :

Code:

FATAL: Error inserting e1000e (/lib/modules/2.6.18-194.el5PAE/kernel/drivers/net/e1000e/e1000e.ko): Unknown symbol in module, or unknown parameter (see dmesg)

And dmesg output :

Code:

e1000e: Unknown symbol vlan_gro_receive

I just overwrite the existing e1000e.ko with my previously built one, the problem might come from this.
I also tried to edit the modules.alias and the pci.map files but it did not do the trick.

Side note : My main goal is to create a new initrd.img to use for our PXE installation process, which does not work as for now because (at least) of the network driver.

oh, and here is the output for the kernel building :

Code:

Oh and when i just built a new module and use it straight away it works like a charms....

Any advices will be very appreciated !
