edit:enough posts to write in dev section, but brainmaster already updated his OP with this information, which is probably the reason you are reading this now.
People are freaking out of the "Random offset XXXX" notification (it is not an error) when they flash an ICS rom in Clockworkmod recovery.
..and so on.
As far as I understand correctly, this is not an error message at all,
but a safety feature implemented in ICS.
So, it might be wise for the OPs to update their first post in any ICS ROM threads to tell people not to be scared.
Thank you koush, brainmaster, kwiboo and frasiscofranco for a very useful ICS ROM and kernel.
