Several issues have been found and recently fixed around the general area of resetting and reloading the GuC, but the driver can still leave the doorbell hardware in an inconsistent state after a reset and reload, such as during a hibernate-and-resume cycle. This set of patches provides solutions (or in some cases workarounds) for the various issues identified in this area.
