One more time: there is only so much I can say about the issue. Richard Relph's message is inaccurate, but I can not describe why or how.
Specific to the subject of this thread: The coreboot (it's not really a BIOS, and yes, I'm splitting hairs) update addresses a Intel-issued "specification clarification" for C2000-based systems. The Intel specification clarification is available at the following location: https://www-ssl.intel.com/content/dam/www/public/us/en/documents/specification-updates/atom-c2000-family-spec-update.pdf This specification clarification includes the following text on page 36: *“If your system does not use SERIRQ and BIOS puts SERIRQ in Quiet-Mode, then the* *weak external pull up resistor is not required. All other cases must implement an* *external pull-up resistor, 8.2k to 10k, tied to 3.3V.”* Since the LPC bus, including SERIRQ is not used in the SG-2xxx, SG-4xxx and SG-8xxx systems, a software workaround for this specification clarification has been implemented by ADI Engineering in v12 of coreboot for the affected systems. The workaround disables SERIRQ to prevent indeterminate interrupt behavior for these systems. The instructions on how to update all affected systems are at the following URLs: https://www.netgate.com/docs/sg-2220/adi-bios-flash.html https://www.netgate.com/docs/sg-2440/adi-bios-flash.html https://www.netgate.com/docs/sg-4860/adi-bios-flash.html https://www.netgate.com/docs/sg-4860-1u/adi-bios-flash.html https://www.netgate.com/docs/sg-8860-1u/adi-bios-flash.html We are also working on a 'package' (for pfSense) that will do most of the work outlined in this documentation. If you aren't running pfSense on your system, then there is a different procedure, please contact Netgate customer support. We have tested this update and believe it to be low risk for you to implement. However, we encourage you to always backup your configuration before applying any update or change. We recommend that you update your affected systems at your earliest convenience. Jim On Tue, Mar 21, 2017 at 3:33 PM, Richard A.
