It works fine on my system, but maybe not with an earlier version of awk, try this:

Code:
awk '/total/{c=11}c>0{c--;print;if(c==0){print "======"}}' file

brute force in ksh works juuuuust fine:

Code:
pattern=droberts

cat /etc/passwd |
while read line ; do

  lines[9]=${lines[8]}
  lines[8]=${lines[7]}
  lines[7]=${lines[6]}

  lines[6]=${lines[5]}
  lines[5]=${lines[4]}
  lines[4]=${lines[3]}

  lines[3]=${lines[2]}
  lines[2]=${lines[1]}
  lines[1]=${lines[0]}
  lines[0]=$line

  if [[ $line = *${pattern}* ]]; then

    for x in 9 8 7 6 5 4 3 2 1 0 ; do

      print "${lines[x]}"

    done

  fi

done
