Thank you Toomas for taking the time. I commented out the two lines you 
suggested and unfortunately not even in that way I have a working kernel. 
When the system tries to boot it just shows the lame symbol "|" and then 
after a few seconds it reboots. I'll go through the configuration file again 
and try to see if something was related to a symmetric multiprocessor.  I 
wouldn't like to disable hyperthreading in the bIOS because what would be 
the point of having an HT processor? Any more ideas from your part would be 
highly welcome.
