No, I think this is a problem with the broken A2 UARTs getting
confused in serial8250_set_sleep(). If I remove either UART_CAP_SLEEP
or UART_CAP_EFR from the capabilities list for this UART, it behaves
normally. Also, just commenting out the UART_CAP_EFR chunks of
set_sleep make it behave. I'll ping Exar for more data. Thanks,
Alex
