This flag adds a pausing utility. When ran with -p, during the kernel probing phase, the kernel will pause after each line of output. This pausing can be ended with the '.' key, and is automatically suspended when entering ddb. This flag comes in handy at systems without a serial port that either hang during booting or reser.
