I'd start saying that you should open a new thread for this issue, but,
doesn't matter...

What's that greg kroah repo you're talking about?

rc3+ looks like it's the kernel version you've already built, which is
likely the default configured kernel that doesn't work for you.
Try to boot the most recent generic kernel, they come with your linux
distro and they should work.
To change the default kernel that boots, search for help/tutorials about
grub configuration in Internet.

After cloning greg kroah hartman's repository from the tutorial , I am
not able to boot into any kernel by default and have to choose from
advanced ubuntu options  from the grub menu . In the advanced ubuntu
options I see generic kernels ,and one rc3+ kernel . I think that's
the one I need to boot in . Am I wrong ? Also when I am trying to boot
in the rc3+ kernel my computer gets stuck and I am unable to boot .
What do I do ? Please help me .

Yes, similar procedure I've followed.
I didn't forget step 4. I actually always did `sudo make

install_modules`. I'm not sure what's going on.

Maybe it has sth to do with Ubuntu, that's why specifically mention I

was using Ubuntu.

Maybe I can try with some other distro. Probably Manjaro has better

support for latest kernel releases.

It's late here. I'll keep trying and let you know in case I figure out

sth.

Ok so probably some modules got missed while building your custom kernel.
Perhaps you can zcat /boot/config-$(uname -r)
and store it as .config to your custom
kernel source location?

Then probably try and remove what you don't need? and see if it works.

Hi Abel,

The procedure I followed in order to compile, install and boot my
custom compiled kernel is:

1. Copy .config from existing distribution to kernel tree.

2. Run make localmodconfig (I also got a bunch of prompts for
parameters I had no idea about. I just pressed down Enter till the
stream of options stopped flowing!)

3. Run make -j<N> where N is a good number for your system.

4. Run make modules_install

5. Run make install (This ran update-grub for me at the end, though,
which was convenient)

That's it. I was able to boot into this newly compiled kernel via
grub's selection menu upon rebooting. I think you may have missed
doing Step 4 above.

Hello,
    If you want to reuse the config of current kernel, you can use
`make oldconfig` to generate config file.

Hello,

you can get .config files in two ways, firstly get the existing
.config file
and compile to kernel.

$ cp /boot/config-x.x.x /bla/linux/.config

Second, use the generate command:

$ make defconfig

Hi!

Where do you get the config file from? or do you generate it

yourself?

Hi Abel,

To add to what Ozgur said, you may first copy the existing .config
file that comes along with your Linux distribution to your kernel
tree, and then use:

$ make localmodconfig

instead of defconfig. A quick Google search should tell you the
differences between the two - and from what I've read,

localmodconfig

quoted

is preferred to defconfig.

Hope this helps.
