so it seems that i m hitting this bug :
https://lkml.org/lkml/2014/4/29/497
+ if (!divisor)
+ divisor = 1;
that have been fixed ( well it looks more like a workaround than a fix
seen from here ) in the 64 bit code but not in the 32 bit code ? I
understand it right ?
is it official that the 32 bit linux kernel is no more supported ?

The data types may be tricking things up a bit. unsigned long is a 64
bit integer on 64 bit systems, but 32 bit integer on 32bit systems.

Maybe some others can shine their light on it.
