re-compile doesn't change anything

geordie

I have re-compiled the kernel to include support for reiserfs but it has made no difference, it reports that the kernel does not support that fs.
I feel I'm missing something in the re-compile.
I deleted the bzImage from the sources file (saving the one in boot to another folder) before recompiling.
I also changed alsa to modules but it is still compiled into the kernel.

What am I doing wrong?

Thanks in advance,
geordie

geordie,

Are you mounting /boot before you copy bzImage there?
Are you installing the modules with make modules_install?

Hi neddyseagoon and thanks for the prompt reply.

I'm doing:
make && make modules_install

I wasn't mounting /boot but I just tried it, copied from linux and rebooted but it's still the same. I can't understand it grub is getting its information from the new bzImage, but ignoring the changes .
Any suggestions?

geordie,

make modules and make modules_install is OK.

Have a look on /lib/modules/<kernel_version>/... and see if you can see the module. Can you modprobe it?

Type uname -a in a terminal to see if you actually are running the new kernel.

Hi
modprobe gives me a complaint of invalid module format - now I'm really baffled.
Worse than that when I did uname -a (thanks for that) it told me the kernel was compiled last Sunday - that was the original compilation of 2.6.5, I've recompiled four times since then with no success. The information for the original kernel must be coming from somwhere else - I didn't think grub was that clever!

I'm really lost.

geordie,

Lets do the kerenl build from the ground up.
Go into the kernel source tree (directly, not via /usr/src/linux) and edit the makefile to change the EXTRAVERSION at the top of the file. Add anything you like to what is already there. geordie ?

Now do make make modules_install.
Mount /boot and copy the arch/i386/boot/bzImage to /boot/kernel-geordie.
Now you have two kernels installed.
Edit grub.conf to include a second block like the 3 or 4 lines that commence with the title line.

In the new block, change the title so you can tell the kerenls apart. Change the kernel name to kernel-geordie, if thats what you used for the new kernel.

Now you have two kernels and two sets of modules. Look in /lib/modules and you will find a directory for each kernel.

Reboot and choose kernel-geordie. If its broken you can always boot your old kernel.

What does uname -a say?
Does reiserfs work now?
