Description:
After upgrading my system with the latest versions of the mesa, intel and radeon open source drivers, Xorg crashes very often. The system which experiences this bug is a Dell Inspiron 7520 laptop, powered by an Intel i7 processor with integrated Intel i815 gpu, and a discrete radeon card. I tried to remove my current /etc/xorg.conf.d configuration, but the bug persists. Upgrading to the current 10.2.8-1 drivers doesn't change anything. The only thing that fixes the problem is downgrading to the 10.2.7-1 drivers.

Additional info:
* package version(s)
local/mesa-libgl 10.2.8-1
local/ati-dri 10.2.8-1
local/intel-dri 10.2.8-1
local/lib32-ati-dri 10.2.8-1
local/lib32-intel-dri 10.2.8-1
local/xorg-server 1.16.0-6 (xorg)

* config and/or log files etc.
Attached, several xorg logs ( after core dumps ) and journal logs.

Steps to reproduce:
Start Xorg. Try to login -> crash and automatically recover
Try to login again, play a video on youtube -> crash, and unresponsive

OR

Work for some little time on a terminal emulator -> crash and unresponsive
Connect to a wifi with wicd -> crash and unresponsive
Etc etc.

UPDATE: Truly, when opening youtube, the keyboard and mouse click events are ignored, while the mouse movements are caught. On such an event, when debugging Xorg.bin with an external computer, and attaching to the running Xorg session, I see that Xorg is still running, and I have to manually interrupt it with a Ctrl-C. Log attached.

Update: the problem seems to be related to my custom kernel. With the core/linux one, xorg works fine. I haven't seen any new kernel requirements in the changelog, though

Update: last stable stock kernel ( Linux the_shire 3.16.3-1-ARCH #1 SMP PREEMPT Wed Sep 17 21:54:13 CEST 2014 x86_64 GNU/Linux ) didn't fix the problem after all. I'm still experiencing it. :(
