Which "console" are you looking at? It only works with the consoles provided by the kernel (ttyN) on usual desktop distros, and not with xterm-alikes. I use ubuntu 11.04 and I use gnome terminal. so you mean what I saw in gonme terminal may not be the ttyN that enabled by kernel? if that is the root cause, is it possible for me to switch my gonme terminal to ttyN you mentioned?
Appreciate your help,
Jonathan refer to consoles you usually get when pressing Ctrl-Alt-F1 throught Ctrl-Alt-F6.
BTW, is there any api I can flush all the messages in kernel buffer ring before when I jump to BUG(), kernel checking MACRO? my problem is: 1. I put more detail messages in the level 8, usually it will shows up if I change console_loglevel or type dmesg. 2. I don't want it to show in normal operation. 3. but I want to see them before my driver jump to BUG() check point. Thanks for your help,
