Description jorgicio 2015-06-14 19:54:15 UTC
Yesterday, the xf86-video-intel-2.99.917-r1 was upgraded with some patches that fix compilation with newer versions of GCC. Since then, running with SNA enabled is broken.
The only workaround I could do, is disabling SNA and enabling UXA, and it works, as I mentioned in

Even I tried with downgrading to 2.99.917, but it also fails. Also recompiled xorg-server and glibc, and nothing happens. I have KMS enabled. Also tried with other session managers (lightdm, slim, etc.), and the result is the same.
I'm using Kernel 4.0.5-gentoo.

Note that the xf86-video-intel used in Funtoo, is the same as in Gentoo, so don't dismiss that!

"also fails" means what exactly? Also crashes? 2.99.917 was not touched at all when bug 550784 was fixed.

Funtoo may have done other strange things to their packages, we don't know. So any Funtoo issues should be reported to their bug tracker.

I don't know, what that's what I got when I downgraded, which is weird at all.

Just some few system packages: GCC, Portage and unrelated libraries to X11 ones. The rest of the ebuilds are the same than the Gentoo ones, so in ebuild matters, Gentoo and Funtoo are (almost) the same. Hence the advice.
Comment 4 Chí-Thanh Christopher Nguyễn gentoo-dev 2015-06-15 00:23:19 UTC
Yes, and the crash happens apparently somewhere in glibc:

Patch that solves the breakage

I applied that patch that I found somewhere in the Opensuse's Bugzilla. It works.
The problem is for people who have the 4.0 kernel.

Thanks to:
Comment 6 Miroslav Šulc gentoo-dev 2015-06-15 06:48:58 UTC
i can confirm both that the issue exists in gentoo and that the attached patch fixes it.
Comment 7 Markus Rathgeb 2015-06-15 07:10:41 UTC
I have done a fresh Gentoo installation on my new M3800 (Intel Core i7-4702HQ with integrated Intel Graphics (HD4600) + Nvidia Quadro K1100M) this weekend.
ATM VIDEO_CARDS is set to "intel i965".
I can start X (xf86-video-intel USE flag was not changed, so sna should be choosen -- will have a look at this evening) without any crash or freeze.

I am using ~amd64.
So, are you using the testing branch, too?

If this patch fixes your freeze, we should (IMHO) apply them.
But perhaps we could wait until someone without a freeze (perhaps myself) test the patch, too. If this breaks my system then we need to further inspect it.

i'd suggest not close this bug until it's confirmed working. This bug impact WAY much of a users assuming amount of Intel cards used.
Comment 10 Chí-Thanh Christopher Nguyễn gentoo-dev 2015-06-15 13:19:13 UTC
The original issue is fixed with this patch according to the reporter per comment #5.

If there are any crashes or other issues remaining, a separate bug report should be opened for them.
