[SOLVED] GDM/Gnome won't start

It's been more than a month now that my computer started to give me an error after booting. Before GDM starts, I get the following message:

Oh no! Something has gone wrong.
A problem has occurred and the system can't recover. Please contact a system administrator

This is not always, I suppose it happens 70% of the time (I need to keep restarting it a few times to get it working). I'm not sure it's a GDM problem because if I CTRL+ALT+F5, login and startx, it'll give me the same error message.

Does anyone have any idea what happened and how can I fix it? I'm running the latest packages.

I don't know which log files might help, let me know and I'll post them.

Any help is appreciated. Thanks.

Edit: here are some logs that might help:

Here you can see at least one failed reboot (the last lines was a sucessful boot ):

$ sudo journalctl -n 1000 -u gdm | curl -F 'sprunge=<-' sprunge.us

http://sprunge.us/KfSf

On this one there's a promising line Sep 18 20:53:07 localhost gdm[400]: Failed to give slave programs access to the display. Trying to proceed.:

$ sudo tail -1000 /var/log/messages.log | curl -F 'sprunge=<-' sprunge.us

http://sprunge.us/fOZU

Am I right to assume Xorg.0.log is from the current session? So I'm pasting the Xorg.1.log, which should be the previous failed one:

$ cat /var/log/Xorg.1.log | curl -F 'sprunge=<-' sprunge.us

http://sprunge.us/OaXL

Hell, it won't hurt if I provide the current one too:

$ cat /var/log/Xorg.0.log | curl -F 'sprunge=<-' sprunge.us

http://sprunge.us/HVPc

Edit 2: I noticed the error only occurs when I get the following message on the boot screen:

[drm:init:ring:common] *ERROR* render ring initialization failed ctl 0001f001 (valid? 1) head 0000b174 tail 00000000 start 00303000 [expected 00303000]
[drm:i915_gem_init] *ERROR* Failed to initialize GPU, declaring it wedged

I could not find this message on the log files, so here is a picture:

Re: [SOLVED] GDM/Gnome won't start

Well, seems to be a problem with the kernel 3.16.x:

I solved it installing the kernel from repo-ck (http://repo-ck.com/), it's all good now.
