Description AnAkkk 2013-01-30 21:11:08 UTC

Since a few days (weeks?), I have been getting some random system lockups. Nothing responds, the only thing I can do is shutdown my computer by holding down the power button. Ctrl+Alt+F keys do not work either. It is pretty random, it can happen at any time.

Kubuntu 13.04 with the xorg-edgers PPA.
Current version of xserver-xorg-input-synaptics: 2:2.20.19+git20130125.8ffb3f50-0ubuntu0sarvatt

Content of Xorg.0.log.old after the crash:

commit 73f574945f2cac14f9bafa6395e2c4dbb16fcf5d
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Sun Jan 27 16:02:52 2013 +0000

    sna: Disable all signals in the render threads
    
    X uses them (SIGIO especially) for input handling, and gets rightfully
    confused if it finds itself in a different thread.
