Bug 753897

When it's in freeze status I can switch to console and read the following log messages:

I can also do a Ctrl-Alt-BS, Xorg restarts but the system remains freeze.
Mouse pointer still respond anyway but I'm not able to do anything.
Just a reboot will make my system work with graphics again.

It's seems to be somehow related to wifi buffer data.
when streaming from yahoo sometimes the streaming stops with no more buffer until I pause the video and data comes in again to buffer. If I do that repeatedly and do scrolling on the browser I increase the probability of freezing.
Maybe the system is not managing properly my video card memory or the system shared memory.

Closing the laptop lit or by pressing the laptop sleep key combination on the keyboard (to hibernate) and open it again (to wake it up) sometimes resolves the X11 crash.

    Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. 

    Please attach your X server config file (/etc/X11/xorg.conf), X server log file (/var/log/Xorg.*.log) and the output of "dmesg" to the bug report as individual uncompressed text/plain file attachments using the bugzilla file attachment link above called "Add an attachment". 

    Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. 

    We will review this issue again once you've had a chance to attach this information. 

    Thank you in advance.
