Good idea. I couldn't get tty_put_char() to trigger nicely, but I just hard coded one to occur, so at least now I know that this doesn't deadlock when called normally. Another suggestion Serge gave off list was to write a kernel module that implemented a driver. I'll see about doing that to see if I can force the original crash. > > Signed-off-by: Tycho Andersen <ty...@tycho.ws> > > Acked-by: Serge Hallyn <se...@hallyn.com> Thanks! Tycho
