kernel 2.6.16

[asundaresan]

Hi,

I'll state at the beginning that I have already read
https://wiki.ubuntu.com/KernelByHandHowto
https://wiki.ubuntu.com/KernelCompileHowto

While these provide a single solution, I am not sure about that it is the best solution for me. I need some new features in my kernel and I wonder what the status of kernel back porting is. For instance can I install an kernel 2.6.15 on breezy?

What is the best solution if I need a newer kernel version?

Suppose I need to compile the latest kernel (2.6.15) in breezy, can I do the following?

$ ls debian/config/i386/config debian/config/i386/config.server > .config
$ make menuconfig
$ fakeroot make-kpkg clean
$ fakeroot make-kpkg --append-to-version -l1 --revision 0 --initrd binary


I realise that this will not be supported, but is there any other option? Is there anything I should be aware of when I do this?

Thanks,
Aravind.

Hi,

I actually used the .config file obtained as described above to make, build and install linux-2.6.16.1 obtained from kernel.org suing make-dpkg. There doesn't seem to be any problem, but there are some errors during boot up such as


insmod: error inserting '/lib/modules/2.6.16.1-l1/kernel/drivers/video/console/bitblit.ko': -1 Unknown symbol in module
insmod: error inserting '/lib/modules/2.6.16.1-l1/kernel/drivers/video/console/fbcon.ko': -1 Unknown symbol in module
insmod: can't read '/lib/modules/2.6.16.1-l1/kernel/drivers/video/softcursor.ko': No such file or directory


during the initial part of the bootup.

However, these modules are indeed present and I can load them after boot up.


aravinds@lerna0:/lib/modules$ find . -iname fbcon.ko
./2.6.12-9-386/kernel/drivers/video/console/fbcon.ko
./2.6.16.1-l1/kernel/drivers/video/console/fbcon.ko
aravinds@lerna0:/lib/modules$ find . -iname softcursor.ko
./2.6.12-9-386/kernel/drivers/video/softcursor.ko
./2.6.16.1-l1/kernel/drivers/video/console/softcursor.ko
aravinds@lerna0:/lib/modules$ find . -iname bitblit.ko
./2.6.12-9-386/kernel/drivers/video/console/bitblit.ko
./2.6.16.1-l1/kernel/drivers/video/console/bitblit.ko


I also get these errors

The system however booted up completely. Are these errors serious?
