Xorg crashes core dump from some reason using todays last verison. 1.17.1-5. I cannot really reproduce this, but it happens many times per day, so this is critical for me, because I use this as a production notebook.

Additional info:
* package version(s)
xorg-server 1.17.1
but I built it here using options=(debug !strip) in the PKGBUILD file - but it happend also before this is just for you to have debuging symbols.

* config and/or log files etc.


Just ask, I will provide all information you may need. And I will try patches for you, if you can give me hints.
This task depends upon

As I see now there is emacs bt in the .xsession-errors.old
You have to know, sometimes its emacs, sometimes its chromium, sometimes firefox, sometimes libreoffice. So this I think cannot be the real reason for the core dump?

Sounds like the TSX bug to me. If you're on a Haswell or early Broadwell processor, make sure your microcode is up to date.

I'm on AMD Quadcore Processor, so I think its not haswell or broadwell - where I haven't heard about that till today...

I also reported that upstream now.

I have the same problem. It seems to mostly happen when I resize frames in certain programs.

I can more or less reproduce it by resizing the frames in 'git gui' but it also occurs in LibreOffice and Emacs.

I'm running on an Intel i5-2500k and use a Radeon R9 290 graphics card with xf86-video-radeon.

xorg-server-1.17.2-3 random crash, I don't know what causes it.
But xorg-server-1.17.2-2 no problem.

1.17.2-1 and 1.17.2-2 are working fine for me.
1.17.2-3 crashes.

I am using ATI Radeon HD 5450 with xf86-video-ati 1:7.5.0-2.

@magicfish1990 @BOHverkill @net147

The patch in release 3 is related to glamor and prime support, if you don't use glamor, problem is elsewhere.
You should open a new bugreport and you should also include a backtrace of the failure:

Please check with xorg-server-1.17.2-4
Comment by Sheng Yu (magicfish1990) - Saturday, 18 July 2015, 08:13 GMT
xorg-server-1.17.2-4 looks stable, 10 hours without crash.
