The chassis, server modules, and NEMs each have a corresponding product notes document that lists known issues with the hardware, software (server modules only), firmware, service processor, and documentation. These documents describe the issues and provide workarounds where possible.
The product notes document is updated with each major software release and often for minor releases as well. Customers should review this document as part of managing firmware.
The chassis product notes also include a list of bugs fixed in each release. A list of bugs fixed is also available on the download page as a ReadMe.
