In the last 10 days Xorg crashed three times with a signal 11 spontaneously. This is the backtrace I found in the logfile:

Fatal server error:
Caught signal 11.  Server aborting

All three crashes happened when I was loading a page in Firefox and after the nightly Firefox builds got switched to Cairo as their rendering backend so I wonder if Cairo could somehow trigger this.

I'm running Fedora Core Rawhide with the following Xorg packages:
xorg-x11-server-Xorg-1.0.99.901-5
xorg-x11-drv-nv-1.1.1-2

I'm using the open source nv driver with the AccelMethod set to EXA and the 'load "dri"' and 'load "glx"' lines commented out.

Just happened again and the backtrace looks similar to the one above. If I can do something to provide better information to debug this please tell me.


Regards,
  Dennis
