Kernel modules are not getting loaded

BenjaminLost · 11-28-2010, 10:39 PM

Hi,

I recently updated the kernel from SLES 11 to SLES 11 SP1 .However my kernel modules are not getting loaded and they throw an error such as shown below:

"Error inserting mii : Unknown symbol in module, or unknown parameter (see dmesg)"

Please, provide some assistance.....

Hi, welcome to LQ!

And what does 'dmesg' say about your modules?

Cheers,
Tink

hey thanks,

The dmesg logs are overwritten on my next boot to a working kernel.
So, I am not able to check the dmesg logs.

Thanks,
Benjamin

dmesg is not a log-file; it's a program (some distros will produce a log
by the same name).

What it the output of dmesg when you try to load one of those modules?

The dmesg shows the following output:-

Probing USB devices: usbcore: FATAL: Error inserting usbcore (/lib/modules/2.6.32.12-5.1.3.default/kernel/drivers/usb/core/usbcore.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and there are similar messages for other modules as well..

So ... when you updated the kernel, did you update the modules
also? How did you go about this update?

I builded the default kernel with built in support for all these modules and used the following set of commands:

make modules_install and make install to get the modules in /lib/modules for the respective kernel.

So, I suppose the modules might have been updated as well..

Did you forget 'make modules_install' ? I had done it once and gotten into a lot of mess.
Hope this helps.

Nopes...i didn't forget it.....i used make modules_install and make install to build the modules and the kernel..
