This happens only if module is being unloaded. If ldisc module is not loaded tty_ldisc_try_get() returns -EINVAL and this case is not handled in tty_ldisc_get(), so request_module() is not called. Attached patch fixes this by calling request_module() if tty_ldisc_try_get() returned any error code. I discovered this when my UMTS modem stopped working with 2.6.27-rc1 because module ppp_async was not loaded.
