Seems like a lot a work and you end up with a unpatched kernel

Code:

[root@main_pc leigh]# uname -r 
2.6.39-0.rc4.git2.0.el6.x86_64
[root@main_pc leigh]#

I used fedpkg to checkout/build the latest from kernel/master

Is there a thread link on how to do this?

Thanks

Try

Code:

su
yum groupinstall "Development tools"
yum install fedpkg rpmdevtools
exit
cd ~
rpmdev-setuptree
mkdir ~/fedpkg_checkout;cd fedpkg_checkout
fedpkg co -a  -B kernel
cd kernel/master
make release
fedpkg srpm
su -c "yum-builddep -y kernel-*.src.rpm"
time rpmbuild --rebuild --with baseonly  --without debuginfo --target=`uname -m` kernel-*.src.rpm

I ran this, and after an initial kernel panic due to overclocked cpu, I restarted it and it all ran through

I have a file in

Code:

~/fedpkg_checkout/kernel/master/kernel-2.6.39-0.rc4.git2.0.fc16.src.rpm

that appears to be what was built...

Do I just install this now?

Sorry for being so naive, I just want to get this first time right...

And I appreciate your help!

Rebuilding a kernel uses all available cpu's to 100% causing lots of heat.

Code:

~/fedpkg_checkout/kernel/master/kernel-2.6.39-0.rc4.git2.0.fc16.src.rpm

That is just the srpm (source code), try looking in ~/rpmbuild/RPMS/`uname -m`/ instead.

Yes... there they are...

Thanks~!

One more question...

When I ran

Code:

su -c "rpm -ivh /home/vastonef15/rpmbuild/RPMS/x86_64/kernel-2.6.39-0.rc4.git2.0.fc15.x86_64.rpm"

I got

Code:

The files are now in the /boot directory and I am about to boot, are these normal messages to see?

Thanks

Thank you so much leigh

Code:

[andrew@localhost ~]$ uname -r
2.6.39-0.rc4.git2.0.fc15.x86_64

Same here...

Thank you leigh! I learned an incredible amount today...

I appreciate it!

I have the file

kernel-devel-2.6.39-0.rc4.git2.0.fc15.x86_64.rpm

also in the /rpmbuild/RPMS/x86_64 directory...

I believe this is what I need to run in order to be able to use virtualbox. with this kernel...

The question I have is do I install it the same way I did the kernel?

Code:

su -c "rpm -ivh --force $HOME/rpmbuild/RPMS/<arch>/kernel-<version>.<arch>.rpm"

You can use yum to install packages that you have built and have locally.

Code:

su -c 'yum localinstall --nogpgcheck $HOME/rpmbuild/RPMS/`uname -m`/SOMEPACKAGE.rpm'

Thank you Andrew.. I appreciate the tip...

# yum install --nogpgcheck http://kojipkgs.fedoraproject.org/pa...c16.x86_64.rpm

I think it's much easier.

That's easy but you wont get the nvidia driver or similar to compile due to the extra debugging.
My method disables the extra debugging (which makes it quicker as well).

You mean you cannot compile nouveau-gallium on this kernel with "my" method?

I mean the proper nvidia driver, the nouveau-gallium is useless with my card.
