-	  BIG FAT WARNING: ENABLING THIS OPTION MIGHT BREAK BOOTING ON
-	  SOME DISTRIBUTIONS.  DO NOT ENABLE THIS UNLESS YOU KNOW WHAT
-	  YOU ARE DOING.  Distros, please enable this and fix whatever
-	  is broken.
-
-	  Conventionally, block device numbers are allocated from
-	  predetermined contiguous area.  However, extended block area
-	  may introduce non-contiguous block device numbers.  This
-	  option forces most block device numbers to be allocated from
-	  the extended space and spreads them to discover kernel or
-	  userland code paths which assume predetermined contiguous
-	  device number allocation.
-
-	  Note that turning on this debug option shuffles all the
-	  device numbers for all IDE and SCSI devices including libata
-	  ones, so root partition specified using device number
-	  directly (via rdev or root=MAJ:MIN) won't work anymore.
-	  Textual device names (root=/dev/sdXn) will continue to work.
-
-	  Say N if you are unsure.
