long boot-up times

hi folks, I have been living with a little irritation for some time now, and it finally dawned on me to ask someone about it. duh. Since upgrading my machines to the suse 9.2 professional boxed set, all of the machines began taking 5 minutes to boot-up... hanging around for a very long time "creating devices" and "setting up kernel module dependencies (if required)". What is the system waiting for? What is the trick to get the boot-up process to fly by like before? This is very consistent from machine to machine; however, once they are booted everything runs great and performance is good. Please help me understand. Thanks. -- Kind regards, Mark H. Harris <><
