Grr, my working kernel is relatively old and panics upon vnconfig
vkernel root image.
But I built a GENERIC kernel and managed to map the backtrace address
to the function name:
begin (0xc0141beb)
mi_startup (0xc029ad61)
vm_mem_init (0xc041bfcc)
pmap_init (0xc04a1286)
kmem_alloc3 (0xc041c500)
vm_map_wire (0xc041fb10)
vm_fault_wire (0xc041b766)
vm_fault (0xc041b602)
pmap_enter (0xc04a37b3)
panic (0xc02bbd53)

Hope this will be helpful
I am uploading kernel image to leaf

Best Regards,
sephe
