fabian,

if you installed from rpm - you could do this

rpm -qa | grep kernel

then whatever it puts out remove the bad one with

yum remove whateverkernel

then reboot and yum update to that kernel again

if it is hand rolled and installed, i dont have the info for you and you
should know how to do that yourself
