Description (partial)

After upgrading ACS to version 5.5, the system is unable to boot. If you see the console of the device, there is only one word "GRUB".

This problem is seen when ACS started at version 5.3, then upgraded to 5.4 and finally to 5.5.
This could also be seen during an upgrade from 5.4 to 5.5 or from 5.3 to 5.5.

The issue will not be seen if we install the pointed patch that has been released specifically for this error before proceeding with the upgrade. The patches can be found in the link :

For upgrade from ACS 5.3, install the patch Pointed-PreUpgrade-CSCum04132-5-3-0-40.tar.gpg
For upgrade from ACS 5.4, install the patch Pointed-PreUpgrade-CSCum04132-5-4-0-46-0a.tar.gpg
