Hi Peter,

I have nearly same machine. I have no problems with X. But the same with
this "silo overflow" this happens many times, and using X-windows too.
Sometimes, after getting this "silo overlow" on X-windows, my screen is
been updated wrong, i have to shutdown and restart X-Windows.

cheers,
emanuel
