Kernel Panic After Cloning (CentOS)
A partition and disk imaging/cloning program

I cloned a multi-partition system from one Dell Poweredge 1850 to another, for a single partition install it all works fine, but for a muti-partition this kernel panic screen appears:
Booting 'CentOS (2.6.17-128.el5)'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.18-128.el5 ro root=LABEL=/rhgb quiet
initrd /initrd-2.6.18-128.el5.img
Memory for crash kernel (0x0 to 0x0) notwithin permissible range
Red Hat nash version 5.1.19.6 starting
Unable to access resume device (/dev/sda7)
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mouting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!
The fstab is:
LABEL=/ / ext3 defaults 1 1
LABEL=/var /var ext3 defaults 1 2
LABEL=/usr /usr ext3 defaults 1 2
LABEL=/home /home ext3 defaults 1 2
LABEL=/boot1 /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
LABEL=SWAP-sdA7 swap swap defaults 0 0
I've accessed the drive using a live CD and the file system is all intact and seems correct, the labels are as they are in fstab, so really I'm getting rather short on ideas!
Has anyone seen anything like this before? And if so, how can it be fixed?
(The multi partition setup is how we setup production servers, so we really need cloning to work with it, so using a single partition isn't an option.)
Thank you for reading,

"Unable to access resume device (/dev/sda7)" -> Did you hibernate your machine before you save it as an image?
BTW, please boot Clonezilla live, enter command line, then run:
/opt/drbl/sbin/ocs-live-bug-report
Please post the generated file.
Steven.
Here is the output of /opt/drbl/sbin/ocs-live-bug-report on the target system:

Did you restore the image to different hardware machine?
If so, maybe you have to update the /boot/initrd*.img.
Also, since you are using old version of Clonezilla live, maybe you can give the latest one, i.e. 1.2.2-31 or even the one in testing branch a try.
//NOTE// Please back up important data before you use Clonezilla.
