>Description:
      The top command displays improperly informative screen (general information lines) where on SMP systems exists in passwd user name longer than 12 chars or on non-SMP systems user name is longer than 14 chars. This applies to standard text console (80x25 chars).
>How-To-Repeat:
      On SMP system:
pw useradd 1234567890abc; top
On non-SMP system:
pw useradd 1234567890abcde; top
