Check for a BIOS update from your vendor. Device registers can be configured and persist despite warm reboot, which implies there is no register reset in driver start or device reset, which further implies that the BIOS can easily affect the outcome. Check also for different behaviour after cold reboot; that is a power down for 30 seconds then power up.
