Tried updating to get r336837 mentioned in another thread, and it still
doesn't help.

Current version is r336859. Partitioning schema looks this way:

=3D>        40  1953525088  ada0  GPT  (932G)
          40      409600     1  efi  (200M)
      409640  1803550720     2  freebsd-ufs  (860G)
  1803960360   148897792     3  freebsd-swap  (71G)
  1952858152      666976        - free -  (326M)

I can boot it when booting from memstick r336739 and setting
vfs.root.mountfrom=3D"ufs:ada0p2".
