To:
My ThinkPad T530 is occasionally having full system lockups, caused by
something Xorg related.  When the system is locked, I am unable to
switch to another tty to kill or investigate.  However, I am able to
move the mouse.  This recently happened while I was sitting in front of
another machine, so I was able to ssh in and retrieve the logs, the
relevant parts of which are copied below (and the full log attached).
As this is my primary system, I have not seen if this exists in other
linuxes or versions of the package.

Unfortunately, this issue is also difficult to reproduce.  My system
just went 20 days between instances.  However, as best as I can tell,
this is set off by something in the Google Chome browser. Typically
lockups seem to happen about when opening a new tab, but I can't pin it
down any further.

Please let me know if there is any other information which might be
relevant.

Steve

Dear Maintainer,
   * What led up to the situation?
        I can fairly easily reproduce the bug by playing minetest on my debian
wheezy system (CPU intensive, some graphics).  It's important to note that my
issue occurred on an Acer Aspire laptop.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        I have not determined a way to reduce the severity of the issue.  Once
Xorg has locked up in this way, I perform the SysRq trick to kill the system.
The problem is that any unsaved changes would be lost when the issue is
encountered.

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***
   * What led up to the situation?
        I have encountered this issue on an Acer Aspire laptop. I encountered
the error while running minetest (a CPU intensive game with some graphics).
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        Once encountering the issue, I could only move the mouse (Ctrl+Alt+F1
didn't work). I could perform sysrq keys.  All of the unsaved work is usually
lost once this occurs, and I can reproduce the issue with an hour or two of
gaming.

Thanks,
Dustin
