View Full Version : [SOLVED] How to install linux 3.0
July 23rd, 2011, 06:51 PM
Hi, I started to upgrade my computer (which has ubuntu 11.4 installed) kernel to 3.0. I tried to compile from source and boot, but I believe something messed up and I had to reinstall Ubuntu. This time I plan to use the precompiled version here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.0-oneiric/ . Can anyone tell me how you install the precompiled version. Any help will be good.

Nevermind, I fixed the problem. I just had to use dpkg with the -i flag.

Yes--- But see below first.
Install it as a debian package > the kernel for your architecture, the header for your architecture and the header all...
Then you are going to want to apply the patch below. The reason you are going to want to apply this patch... Because of the numbering shema change, it's going to be challenge afterwards:
- The kernel numbering schema changed for this kernel.
- Debian packages check the kernel numbering schema for a range before installing or compiling to ensure that it's going to be able to work for the kernel it was intended for.
- Recent kernels prior to the 3.0 series kernel, was set to 2.4.x, then 2.6.x...
See where that version check limit needs to be changed? Oneiric already includes this patch. (You are running Natty.)

rcu: avoid build error for third-party modules
The initial definition of __kfree_rcu() checked a static inline function argument to see if it was a compile-time constant. Apparently not all compilers are willing to put up with this at all optimization levels. Add a nasty comment and remove the warning, relying on the fact that __kfree_rcu() is called only from kfree_rcu(), which always passes in a compile-time constant.
