It turned out\nthat the jiffies clocksource is used in early boot before it is registered,\nwhich leaves the max_delta_raw field at zero. That causes the read out to\nbe clamped to the max delta of 0, which means time is not making progress.\n\nCure it by ensuring that it is initialized before its first usage in\ntimekeeping_init()."
