thanks a lot for your feedback. It seems we solved the problem: it was 
the power supplying unit! We change some stuff (memory, cleaned the 
machine and so on), but after changing the power supplying unit, 
everything worked fine. So I guess the new kernel just had a little bit 
more power consumption than the previous one.

Thanks a lot for your kind help, and sorry for the false alert! :-)
