[gentoo-dev] Dropping stable USE flags for 4.14

[gentoo-dev] Dropping stable USE flags for 4.14

[Alice Ferrazzi]

Hello,

We have recently started the stabilization of gentoo-sources-4.14.8.

Very soon we received reports regarding broken e1000e driver [1] and moved
to gentoo-sources-4.14.8-r1.

Since then we keep receiving new problems related to 4.14.x kernel:

- IPSec is broken [2]

- Change in 4.14.9 broke nVIDIA driver [3]

- Colors on console are broken with some Radeon HD cards [4]

- BUG report on boot [5]

- Unbootable system with CONFIG_MCORE2 [6]

- ...more bugs [7]

While not all issues are present in gentoo-sources-4.14.8-r1 we are
concerned about the current stability/quality of the 4.14.x branch in
general and don't feel comfortable recommending 4.14.x branch for general
use at the moment. But that's what a stable USE flag means for most
Gentoo users.

So, for now, we have decided to drop gentoo-sources-4.14.x stable keywords.
We will keep watching 4.14 branch and once the stability/quality matches
our requirements we will restart stabilization.

Keep in mind: We are only dropping stable USE flags. If
gentoo-sources-4.14.x works for you and you want to keep it, just keyword
the package on your own!

4.14.9 prevents both my desktop and my server from being boot, hangs
very early in the process before dmesg could start.

Tried to bisect itm, w/o too much success, would have much more
difficulties to bisect the remote headless server.

Whilst both systems boot now again (I mainly had to switch to the
generic CPU instead the Intel MCORE2 config option and removed few extra
sanity chekcs and the GCC plugin and so on) I second you about the
quality of the current 4.1.4.X tree, especially for X>=9.

I complaint already at the LKML.

I'd suggest dropping stable for 4.12 too for the moment and instead 
stabilizing newest 4.9. 

(I had some hard crashes of my laptop with 4.12... since then running 4.9 
everywhere and very happy with it...)

Be careful, you don't want to drop back to older kernels with known
security issues that are already fixed in the latest 4.14.y release.

Most of the above issues have resolutions already, and yes, 4.14 is
being a bit more "temperamental", sorry, it will pay off in the end...

This turns out to be a gentoo-specific bug, not much upstream can do
about a broken compiler that some profiles are using :(
