Mesa card 7i90 xilinx PhysDesignRules:2410

Hello, please can you help me, I make the config file and use ise desing 14.5 and got the warnig

PhysDesignRules:2410 - This design is using one or more 9K Block RAMs (RAMB8BWER).  9K Block RAM initialization data, both user defined and default, may be incorrect and should not be used.  For more information, please reference Xilinx Answer Record 39999.

Does this warning affect normal operation?
Thanks.

If you are using ISE >13.1 it only matters if encryption is used (its not)
I actually don't think it matters even on ISE < 13.2 as it seem more related
to Xilinx's core generator (which the source does not use for portability reasons)

ok, thanks.
