This happens almost every other time I boot CURRENT

SMP: AP CPU #1 Launched!
panic: mutex Giant not owned at /usr/src/sys/vm/vm_page.c:774
cpuid = 1; lapic.id = 00000000
Debugger("panic")
Stopped at 		Debugger+0x4e:  xchgl	%ebx, in_Debugger.0

I am going to update again tonight and see if there are any changes... 
This is
from Sunday morning.
