NetScreen 5400 problem

Hello everyone,

I have a NetScreen 5400 with M2 management module.
At the login via the CLI appears the following message: "PCI Master Data parity error on Req queue read". I can login and execute commands but the message keeps popping up continuously. In addition, CPU usage remains above 70%. There are not any errors in the log. I reset the device and downgrade the firmware but the problem persists.

Does anyone know how to solve this problem? Can it be a hardware problem of the management module or of another module installed? Maybe a software problem?

Thank you for your answers. I need help!!
