Panic String: vm_page_insert: page already inserted

#2  0xffffffff808ffa47 in panic (fmt=0x1 <Address 0x1 out of bounds>)
    at /stub/src/sys/kern/kern_shutdown.c:642
#3  0xffffffff80bdde24 in vm_page_insert (m=0xfffffe007e1797f8, 
    object=0xfffffe003b23a658, pindex=4089) at /stub/src/sys/vm/vm_page.c:915
#4  0xffffffff819586d0 in rtR0MemObjFreeBSDContigPhysAllocHelper ()
   from /boot/modules/vboxdrv.ko
#5  0xffffffff81958796 in rtR0MemObjFreeBSDPhysAllocHelper ()
   from /boot/modules/vboxdrv.ko

Earlier stacks:
3x	rtR0MemObjFreeBSDAllocPhysPages, rtR0MemObjNativeAllocPhysNC
1x	rtR0MemObjFreeBSDAllocHelper, rtR0MemObjNativeAllocLow


No idea.  Probably either a problem in vboxdrv.ko or a problem in 9.2-STABLE,
since all panic reports involve both of these.
