  Now kernel gets built, but still fails to load under either Xen 3.5 or Xen 3.4.1.
  Stack traces differ on C2D E8400 (Xen 3.4.1)  and Q9550 (Xen 3.5 unstable )boxes.
  On the last box :-

 do_one_initcall + 0x37/0x1a0
 kernel_init + 0x164/0x1ba
 child_rip + 0xa/0x20
 ? int_ret_from_sys_call 0x7/0x16
 ? retint_restore_arg + 0x5/0x6
 ? child_rip 0x0/0x20

 Two last commands are the same on the first box. Previous differ.

Boris.
P.S. I cannot buy or order 20 m of NUL modem cable.
       Just 2.5 m . That's all
