I wonder if this means that 3.14 will make it into Ubuntu 14.04. Would be nice not to have a franken-kernel for a LTS release.

Ubuntu 14.04 already uses 3.14 kernel in daily images. You can download the .deb from here. http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/

It's possible, as the Kernel Freeze is on April 3rd (https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule).

I would assume that 3.12 would be used instead since it's the latest long-term stable release of the kernel.

FWIW I'm already using 14.04 beta2, and the kernel there is 3.13.0-20. This means the stable version will be 3.14, doesn't it?

Why would you conclude that?

I remembered odd versions were unstable, but looking at the kernel info, 3.13 is a stable version. So I'm guessing they'll stick with that.

> I remembered odd versions were unstable

this stopped being true very long ago (with the beginning of the 2.6 series)

TIL :)

Kernel freeze is April second so this means that they "should" be able to update the kernel to 3.14 but its Ubuntu and you never know.

I think that would then be the first time that Ubuntu LTS is piggybacking on an LTS kernel. With 3.12 already 6 months old that seems unlikely to me given Ubuntu's usual attempts to support modern hardware.

If they don't use 3.14 they won't have complete Intel broadwell support. Since those chips will come out and be the primary source of new 14.04 installs, they either need to release a point release with a new kernel around the product launch or get 3.14 in now.

Of course they could backport those patches to their kernel.

The kernel and X stack get regular backports over the life of the LTS release (since Precise):

I upgraded to the 14.04 LTS beta and uname -r returns 3.13.0-19-lowlatency for me.

No risks for an LTS release I guess.

Bummer. On the flip side, maintaining a franken kernel for multiple years isn't fun either so one would think this be a pro in favor of 3.14.

Oh well, at least OpenSSH 6.6 made it in.

LTS releases should probably stick to a kernel that will have long-term stable support. One example is GKH's (Greg Kroah-Hartman's) stability kernels: http://www.linuxfoundation.org/news-media/blogs/browse/2013/...

Understandably launching ubuntu 14.04 with and older kernel is less than ideal, but launching on a kernel that will lose support in 6 months is probably a worse idea.
