Question Kernel installation problem


ALL,

I am trying to install linux kernel 2.6.33.9 on Centos 6.3.
I install the kernel and then I get the following errors after the make install.

ERROR: modinfo: could not find module bnx2fc
ERROR: modinfo: could not find module mxm_wmi

I reboot the machine and internet does not work. I believe it is because the bnx2fc(NIC) module had an error loading.

Is there a way to correct this?

I did follow that procedure. The problem that I have is the missing modules at the end. Centos is recommending not to do a real time patch or any kernel modification. So it seems there might be a lot of problems with kernel compilations.

I am mainly trying to solve the problem the getting all modules.

You can probably download the modules you need as RPM files. Looks like the NIC module can be found from any CentOS mirror according to this: http://lists.centos.org/pipermail/ce...il/018590.html.

The following updated files have been uploaded and are currently
syncing to the mirrors: ( sha256sum Filename )

I am still getting the error of not having an internet connection when booting into the new kernel.

I did the rpm -i kmod-bnx2fc-1.0.10-1.el6_2.i686.rpm. I rebooted and still no connection.

Once I do the rpm install do I have to rebuild the kernel?

I don't know much about Centos, but have you tried 'make && make modules_install'? That's my normal method of compiling a kernel. Obviously you must tick the necessary box for your modules in the config file.

I already did that. I believe the problem is that the kernel I downloaded from www.kernel.org (2.6.33.9) does not have the bn2xfc module with it. I looked in the config file and I did not see any options for the module.

Do you know what these modules do? If you don't need them then omit them from your "menuconfig". Untick the boxes.They are not included in my kernel(3.7.10-gentoo), so they must be specific to a particular piece of hardware.

If you do need them, then if you haven't done it already, you should install the complete kernel source, execute "make mrproper" and compile from that. You can 'fine tune' the kernel once you have something that runs.

If you are not sure what modules you do need, try running a live CD and see which modules that uses. Another thing you could do is to take the config file given by a live CD and load that in to your kernel source code. (Load an Alternative Configuration File).

Just realised that you are working on quite an old kernel. kernel 3 has been around for some months now. Can't you find one of them to work on?
