Recently I update a server running CentOS 4.3 to kernel

LVM partitions, showing the follow error during boot:

Root partition is a LVM2 on Software RAID.
With old kernel (2.6.9-34.0.2) the system boot normally.
do you have any custom drivers that are missing in the new kernel ? ( eg. what drive interface controller are you using ? )
