Re: WARNING: at drivers/tty/tty_buffer.c:476 flush_to_ldisc()

[Sedat Dilek]

Hi Dave,

I suspected after initial testing a problem in TTY and applied two patches.
After more testing the root cause was a problem in JBD2.
A patch from Eric helped!
Follow the thread in [1] for more details.

If you are on Linux-Next (next-20130118) you need the following three patches.

Ilya Zykov (2):
      tty: Correct tty buffer flush.
      tty: Add driver unthrottle in ioctl(...,TCFLSH,..).

Eric Sandeen (1):
      jbd2: don't wake kjournald unnecessarily

Hope this helps you.

Regards,
