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! :-) Florian
