I'm getting the following message on a Cisco WS-SUP720-3B when booting up.

"RELIABILITY DRIVER: wrong signature on NVFLASH"

All diagnostics pass and the Sup seems to be working fine.  Has anyone else seen this message?  Can you tell me why it is displayed?

    I am gueesing here, but I have seen somthing like this before. Cisco flash is just memory like you buy at best buy however it is different in the fact that it uses different addressing than normal ram. The fact that it says wrong signiture is an indication that it is not seeing these diferent adressing points. So I would say that either someone has stuck a standard peice of RAM in one of the slots, or somthing has corrupted the file system one of the simms and it will need to be replaced.

    Does your switch have more than one supervisor engine in it?
