module cbb already present

Hello.

	In todays kernel there is some message which doesn't present on Aug 9 
kernel (marked with empty lines). My kernel config didn't change.
/boot/loader.conf is empty.

	Also this kernel stops after 'Pre-seeding PRNG:' message and stops 
until I enter DDB. I can press any keys and they are displayed at the 
screen. Ctrl-C doesn't work. I dont have a console at the moment, I will 
post output of DDB trace, show threads, show locks and ps in monday. I 
wonder if anyone else see this?
	It goes fine into single user mode. When I exit single user shell, it 
boots fine.
	Witness enabled, preemption disabled, htt enabled, SMP kernel, ACPI 
enabled (when disabled, it panics at boot btw), cleanworld before
buildworld, debug.mpsafenet=0 or 1, it doesn't matter on this subject.
