can't boot after upgrade

[kk]

Upgraded my fc2 to fc3, the result is that i can't boot into Fedora anymore.

When i boot i see that audio etc is started, then the misery begins:
First "configuring kernel parameters" just hangs, nothing happens, when 
i hit ctrl +c the boot process continues, with errors like:
"touch: cannot touch /var/lock/subsys/kudzu",
"touch: cannot touch /var/lock/subsys/network",
"touch: cannot touch /var/lock/subsys/firestarter",
then "starting system logger" hangs, no response with ctrl+c, 
ctrl+alt+del works though

any help appreciated, do i have to reinstall?

grrr
