Without this patch, the wrong text is drawn into these lines, corrupting the display. Observed in 2.6.14 when running an IRC client in the Nintendo DS linux port. I haven't tested if scrolling down has the same problem.

Miller" Date: Fri, 9 Jun 2006 11:58:36 -0700 Subject: [TG3]: Handle Sun onboard tg3 chips more correctly. Get rid of all the SUN_570X logic and instead: 1) Make sure MEMARB_ENABLE is set when we probe the SRAM for config information. If that is off we will get timeouts. 2) Always try to sync with the firmware, if there is no firmware running do not treat it as an error and instead just report it the first time we notice this condition. 3) If there is no valid SRAM signature, assume the device is onboard by setting TG3_FLAG_EEPROM_WRITE_PROT. Update driver version and release date. With help from Michael Chan and Fabio Massimo Di Nitto. Signed-off-by: David S.

I have managed to reproduce the problem, and the patch below fixes the actual cause. The problem is not in fact in ppp_async.c but in n_tty.c. What happens is that when pptp reads from the pty, we call read_chan() in drivers/char/n_tty.c on the master side of the pty. That copies all the characters out of its buffer to userspace and then calls check_unthrottle(), which calls the pty unthrottle routine, which calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup, which calls tasklet_schedule. So far so good. Since we are in process context, the tasklet runs immediately and calls ppp_async_process(), which calls ppp_async_push, which calls the tty->driver->write function to send some more output. However, tty->driver->write() returns zero, because the master tty->receive_room is still zero. We haven't returned from check_unthrottle() yet, and read_chan() only updates tty->receive_room _after_ calling check_unthrottle. That means that the driver->write call in ppp_async_process() returns 0. That would be fine if we were going to get a subsequent wakeup call, but we aren't (we just had it, and the buffer is now empty). The solution is for n_tty.c to update tty->receive_room _before_ calling the driver unthrottle routine. The patch below does this. With this patch I was able to transfer a 900MB file over a PPTP connection (taking about 25 minutes), whereas without the patch the connection would always stall in under a minute.
