RELENG_7/amd64: booting from gpt failed.

[Dmitry Morozovsky]

Dear colleagues,

I'm trying to set up new machine with RAID array slightly larger than 2T, so 
I'm forced to use gpt.

I did successfully 

gpt create
gpt boot
gpt add 
newfs 
tar base system

gpt show output looks like:

       start        size  index  contents
           0           1         PMBR
           1           1         Pri GPT header
           2          32         Pri GPT table
          34         128      1  GPT part - FreeBSD boot
         162     1048576      2  GPT part - FreeBSD UFS/UFS2
     1048738    33554432      3  GPT part - FreeBSD swap
    34603170  4359862077      4  GPT part - FreeBSD ZFS
  4394465247          32         Sec GPT table
  4394465279           1         Sec GPT header

and I hope it boots from da0p2, but it fails:

               /boot.config: -Dh -S115200

can't load 'kernel'

Type '?' for a list of commands, 'help' for more detailed help.
OK ls
bad path ''
OK show loaddev
disk0s2`:
OK show currdev
disk0s2`:

Quick googling does not help much. 

Any hints? Thanks in advance.

Sincerely,
