printout of uname -a ?
It is not exactly a vanilla kernel - the vanilla was 2.6.31-rc5 - the team has modified it. Specifically, feedback is wanted for the kernel modesetting and adoption of UXA for intel cards.

The final ubuntu kernel has not been made yet.

Could you provide some more detail:

Which release candidate (alpha, beta, netbook, server, etc)?

Are you saying that the default install uses a vanilla kernel instead of the Ubuntu kernel?

Which 2.6.31 kernel is being installed?

None of them are shipped with a "pure" vanilla kernel so I suspect we are looking at a misunderstanding.

2.6.31 ships with alpha 4 as 2.6.31-5.24 which is based on "vanilla" kernel 2.6.31-rc5

The specification is at:
https://blueprints.launchpad.net/ubu...armic-flavours

It is possible that uname -r will return the kernel version sans "-generic" which you'd normally see or that OP has read promo which just says 2.6.31 - which would be a vanilla designation - and did not grok that it was just shorthand.

alpha 3 had 2.6.31-3.19 kernel based on 2.6.31-rc3
alpha 2 had 2.6.30-5.6 kernel based on 2.6.30-rc5

another possibility is that the release was not from an official source.

As Simon says, this is a misunderstood.

Long ago were odd for vanilla/testing and even for stable release. Now all the branch 2.6.x is stable, no matter what x is, even or odd.

So, basically I was asking a question related to an old paradigm.

Thanks to all.

A vanilla kernel is what you get off kernel.org
A distro kernel is the one shipped with a distro to the maintainers specs.

Vanilla kernel
http://www.linuxquestions.org/questi...-kernel-79388/

Even-Odd numbering scheme
http://en.wikipedia.org/wiki/Softwar...pment_releases
http://en.wikipedia.org/wiki/Linux_k...sion_numbering

Used to be that 2.B.C was testing/unstable for B is odd.

With the 2.6 kernel and the shorter release cycle, the C number plays the previous role of the B number, except for the even-odd scheme. Instead you'll see -rcn on the end for release candidates expected to be unstable and peoples initials for specific development branches.

Great explanation.
