CentOS - Sep 2006 - 2.6.9.42 Kernel Panic

I just joined the mailing list after seeing this e-mail in the mailing
list archives.  Does anyone have any idea as to why this may be
happening?  I am having this exact problem on a Dell Poweredge 1855.

Recently I update a server running CentOS 4.3 to kernel 
2.6.9-42.0.2. After the update it had a problem to mount
LVM partitions, showing the follow error during boot:
 
  No volume groups found
  Activating logical volumes
  Unable to find volume group "lvm1" 
  ERROR: /bin/lvm exited abnormally! (pid 199)
  Creating root device
  Mounting root filesystem
  mount: error 6 mounting ext3
  mount: error 2 mounting none
  Switching to new root
  switchroot: mount failed: 22
  umount /initrd/dev failed: 2
  Kernel panic - not syncing: Attempted to kill init!
 
Root partition is a LVM2 on Software RAID.
 
With old kernel (2.6.9-34.0.2) the system boot normally.
 
Any idea what is error?
 
Best regards
 
Heitor Augusto

do you have any custom drivers that are missing in the new kernel ? ( 
eg. what drive interface controller are you using ? )
