So RX IRQ fire and both RX and TX are disabled, sure that's bad. But it should cause lower throughput. At a minimum, I think your commit log needs some work. Also, disable_irq_nosync() shouldn't really be needed, you could just mask the IRQ in the IRQ Enable register, but I guess that'd be v4.3 material. -- balbi
