I have discovered new things about this issue. I discard that is a
problem with the Linux kernel. I have tried the 2.6.26 with
Mathematica

7.0.0

$Version: 7.0 for Linux x86 (64-bit) (November 11, 2008)

and 7.0.1

$Version: 7.0 for Linux x86 (64-bit) (February 18, 2009)

and I am getting floating point exceptions again. The problem is
related with the new Core I processors of Intel. This machine have
four processors intel(R) Core(TM) i3 M 330 @ 2.13GHz and Wolfram is
giving patches:

http://support.wolfram.com/technotes/IntelCorei7.html

According to Wolfram it seems that the affected machines are only i7
processors (Windows and Linux)  howvever I think that also it is
possibly affecting the i3 processors.

Somebody knows more details about how Wolfram are managing the
patches?
