>Description:

I have a DOS EXT LBA partition with several other partitions (all as EXT LBA
in the chain), but just first is recognized, because continuation is allowed
just for DOS EXT (non-LBA). Following patch helps to find all extended
partitions on my disk, but I'm not sure, if it is sufficient - however,
it seems that it works.
