Hi I don't see anyone in kernel using UART_IIR_BUSY bit except Designware serial driver. We are using 8250 driver for our 16550A and occasionally we see UART_IIR_BUSY set and soon after that console is hosed. In what situations is this bit set? I don't see much documentation for this. Appreciate any help. thank you. -- 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
