Symptoms are caused by gpu hang (your graphics card is running in a forever loop). Same time driver is waiting for signal from the card that operations have done. So result is that the driver gets blocked which blocks most of others parts of kernel too.
Only solution to aoid this situation is to use the newer KMS driver which has detection system for GPU hang.
