If it's reproducable can you test whether adding the unlock/relock in drivers/tty/pty.c does the trick ? ie: tty_unlock(tty); tty_vhangup(tty); tty_lock(tty); or if changing it for tty_hangup(tty) does it. There's some kind of lurking circular locking deadlock that I've not managed to trigger here but a couple of reports point towards. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
