Xorg Segmentation Fault for Kernels 4.x [solved]

I'm out of ideas how to fix the problem, please my logs, I hope somebody can decode what could possibly be the underlying problem.

http://pastebin.com/DZq6jxXS

I'm not sure if I missed any kernel config, tried rebuilding glibc because a line tells me it segfaults there. Rebuilt xf86-video-intel and nvidia-drivers - still no luck. Re-emerge x11-drivers/* that I use, xorg-server, etc... still no luck.

Tried gentoo-sources too, still no luck. Hope someone can help.

I am stuck with 3.19 (debian-sources), however, I can't make my hdmi and displayports to work. xrandr -q does not report anything related to HDMI and DPs.

Thanks in advance.

you are calling for issues using 3.19 or 4.x.x anyway.

3.18 is the longterm kernel and should give you security fixes and less hassles regarding nvidia-drivers / xorg-server ...

only gentoo-sources are supported by gentoo anyway afaik ... so using 3.19 debian ...

I see it on my second box where i run 4.x.x kernel. too often ihave to recompile my kernel because it popped out of the kernel tree. where my 3.18 kernel here is still in the tree and marked green. that just costs time and rebuilds for some modules and is just a time waste for nearly no benefit at all, in my expierence ...

r00t440,

Is this a Funtoo install?

Two bug reports are possibly relevant to your problems:

bug 552124
bug 556264

You may want to check them out and see if these apply to your configuration.

@tw04l124
Thanks for the info... well, I seem to be having problems with alx (Atheros) module on 3.1x kernels. I'm assuming that it would somehow be more stable on 4.x kernels. Also, I'm having issues with HDMI and DisplayPorts not being "seen" by Xorg. I am hoping or would like to see if using a 4.x kernel would solve these problems.

@NeddySeagoon,
Yes it is a Funtoo install, also posted same topic in their forums. Thanks!

@chithanh,
Thanks a lot for these links, havent tried UXA accel method. You gave me extra options to fiddle with.

Cheers!

please post funtoo stuff in unsupported. as we use different ebuilds and it may not even happens here than.

funtoo is definitely not gentoo. even their toolchain is different according to their homepage.

Moved from Kernel & Hardware to Unsupported Software. Not about Gentoo so it fits better here.

thanks... so far, it works now.

the workaround is to use UXA instead of the faster SNA. As a side-effect, you'll have video tearing using UXA.

Solution:

Add this line in /etc/portage/package.accept_keywords
