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.
