Tegra appears to boot with function UARTA pre-selected on mux group SDB. If two mux groups are both set to the same function, it's unclear which group's pins drive the RX signals into the HW module. For UARTA, SDB certainly overrides group IRTX in practice. To solve this, configure some alternative function on SDB to avoid the conflict. Also, tri-state the group to avoid driving any signal onto it until we know what's connected.
