>Description:
Using disklabel -i for a disk with more than 1 TByte, a partition cannot be set 
for more than 1 TByte interactively, i.e. the number of sectors is limited to 
2**31, whether given as sectors, cylinders or Megabytes.

Here is a (Cyl. removed for readability) sample session:

>How-To-Repeat:
Use a disk with more than 1TB, allocate all to a partition, and try to enter 
interactively a size of about 2200000000 sectors.
>Fix:
Write disklabel to disk, edit file, and restore
