 OK, the problem seems to be that one of the variables in the calculation has
 overflowed.
 When used in the calculation it causes the "integer divide fault".
 
 Possible solution:
 
 I'm testing if a change of the variables involved to long will fix this.
 It is definately caused by the avgfilesize setting.  If it's high it will
 wrap when multiplied with the fs_avgfpdir value.
 If we asume the average files per directory is 64, we see that a setting of
 67108864 or higher for average file size, will overflow the int.  I was
 using 256000000 wich is 188891136 too much.
 
 I think ALL variables in this section (and the rest of the filesystem
 source) shoulr all be long or similar.
