Re: CentOS 4.4 & smp kernel?

Hi,

this is a known problem with recent CentOS/RHEL SMP kernels. The source 
of the problem is a patch applied to the kernel by Red Hat. That patch 
changes some definitions in the kernel headers and these changes call 
GPL only symbols, which is problematic for non-GPL kernel modules like 
DriverLoader.

To solve this problem, please use the "stk16" kernel available at:

i586: 
http://www.linuxant.com/driverloader/wlan/full/downloads-rhel40-i586.php
i686: 
http://www.linuxant.com/driverloader/wlan/full/downloads-rhel40-i686.php

We have disabled this problematic patch in our 16K stacks builds. This 
patch is only useful if you want to do kernel debugging as far as I know 
and should not have a negative impact on your system.

You can also try vanilla kernel from http://www.kernel.org if you prefer 
or use a non-SMP kernel if you have a single CPU with a single core.

Driverloader's been working flawlessly with the builtin Dell 1350 WLAN card on the d800 with CentOS 4.x with all kernels that I have been using, but after installing on the d820 with an smp kernel the driverloader module doesnt seem to want to load.  It gives the following error:
