If device paths are not correctly setup by the UEFI
implementation we may and up with a partition whose
parent is not the block device.
To make things easier do analyze add a debug message
EFIBLK %#02x %s is not a child device of %s
The output might look like this:
EFIBLK 0x80 /HD(1,MBR,0xa6d56afb,0x800,0x3f800)
is not a child device of
/HD(1,MBR,0xa6d56afb,0x800,0x3f800)
