kernel >2.6.30.2 and networkmanager

**Nisok** · 08-30-2009

Hi to all!
I face the following problem, which I don't know if it is an ubuntu or kernel or networkmanager problem.

I compile kernels from the v. 26.30.2 until the latest ...30.5 but each time the networkmanager doesn't work!

Using the

Code:

 lspci -nn

I can see that my network cards are correct, but the

Code:

 ifconfig

command doesn't return the usual interfaces. When I which back the normal ubuntu kernel everything is up again.

Could anybody help me?

Hi Nisok
When building your kernel, did you do a 'make clean' and were there any errors or warnings with the compile. Sometimes compiles are forced to complete even with errors and this can get forgotten in makefiles, until something doesn't work.
It is possible, particularly with Dynamic Linked Compiles, that certain libraries are not suitable for the newer kernel. You are you know on the 'bleeding' edge when you compile your own kernel.
Actually don't feel bad as lots of developers have jobs because of these problems. Cheers...

Sounds like your modules aren't loaded. Do you know what you used before? forcedeth, b44, ath_pci?

Yes I used clean. Actually I did

Code:

 make-kpkg clean

What I did was to remove all the pci drivers that I don't use and the rest I compiled inside the kernel. I try not to use modules for PCI devices.
