Bug #1887: System freezes with syscons screen saver on and a high CPU load

Hi,

I'm running v2.9.0.68.g57eab-DEVELOPMENT on an M4A78L motherboard with a Phenom II 955 (quad core 3.2 GHz), however this has been happening for a while but it's only now that I've pinned down the circumstances.

If I have the logo-saver running and displayed on the console then anything that generates a high CPU load (make -j 8 buildworld in an ssh session from another box does nicely) will lock the system up solid when the logo reaches a certain point near the top right hand side.
Once locked the system is completely unresponsive to network or keyboard, only a reset or power cycle will unlock it. Without the logo_saver running the system is as
solid as a rock.
