Default Re: NVidia live-lock with Xorg and app on ws460c HP Blade Workstation with Quadro 600

Watching an strace of the X process before triggering the hang, we definitely halt in an ioctl call on /dev/nvidiactl

The application is spinning on access to the socket it uses to communicate with the X server.

I also sometimes see this in Xorg.0.log:
