This used to behave well > before. I don't have time to investigate that one right now though. Going through it I found one assumption in the tty_port code that wanted fixing. We would release the port and then try to change the modem lines. The dtr_rts method didn't claim the function which in conjunction with that made it crash. Also the hangup checked your old port->opened which now never got set. I am scratching my head over some of the other stuff I found however. In particular port->func can be set to NULL when the device is removed. The claim method takes the mutex, checks if it is NULL and acts accordingly but it releases the mutex, which makes it useless as the code then uses port->func. If I move the release of the mutex to the release_func method then that fixes almost all cases. The one I'm stuck on is this CPU1 CPU2 sdio_uart_irq sdio_uart_port_remove port->func = NULL; sdio_in BUG_ON I'm not sure what the required rules on the irq disable/remove are meant to be here ?
