Which means that someone has tty->low_latency set and is calling tty_flip_buffer_push in an IRQ. That has never been allowed or safe, and now it hurts ;) /** * tty_flip_buffer_push - terminal * @tty: tty to push * * Queue a push of the terminal flip buffers to the line discipline. This * function must not be called from IRQ context if tty->low_latency is set * * In the event of the queue being busy for flipping the work will be * held off and retried later. * * Locking: tty buffer lock. Driver locks in low latency mode. */ That comment has been there for some years in varying formats _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
