Thanks for looking into that. I was too lazy to do that on Sunday. You're right that it may cause problems. Fortunately vt doesn't refcount ttys. Hence con_shutdown can be called only from release_tty (close path) in the user context. Adding to my TODO list, unless somebody beats me to fix it. thanks, -- js suse labs ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
