 After a weekend testing kernel configurations, I have found the cause
 of the reproduceable total kernel-freeze on my system. It's the                 
 combination of                                                                  
 device          pcm                                           
 
 and                                                                             
 
 # USB support                                                                  
 device          uhci            # UHCI PCI->USB interface        
 device          ohci            # OHCI PCI->USB interface
 device          usb             # USB Bus (required)
 device          ugen            # Generic   
 device          uhid            # "Human Interface Devices"
 
 Without these USB entrys (I havn't tested each single entry, it's a        
 workaround for me to comment all out, because I dont use USB) Sound
 works. With these USB entrys, theres a total System freeze at boot-time, 
 resp. by loading snd module.
