. remove some call cycles by low-level functions invoking printf(); e.g. send_sig() gets a return value that the caller should check . reason: very-early-phase printf() would trigger a printf() causing infinite recursion -> GPF . move serial initialization a little earlier so DEBUG_EXTRA works for serial earlier (e.g. its first instance, for "cstart") . closes tracker item 583: System Fails to Complete Startup with Verbose 2 and 3 Boot Parameters, reported by Stephen Hatton / pikpik.
