Hi Linux serial maintainers, There appears to be a bug in 8250_dma.c where __dma_rx_complete is passed to the dmaengine as the completion callback for rx dma. __dma_rx_complete does not lock the port spinlock (since it is also called in contexts where the lock is already held). So a wrapper around __dma_rx_complete which does lock the port spinlock should be used as the completion callback instead. -- Frank -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
