When there is pending signals, current spufs_run_spu() always returns -ERESTARTSYS and it is called again automatically. But, if spe already stopped by stop-and-signal or halt instruction, returning -ERESTARTSYS makes stop-and-signal/halt lost and spu run over the end-point. For your convenience, I attached a sample code to restage this bug. If there is no bug, printed NPC will be 0x4000.
