>Description:

PPP ( /usr/sbin/ppp on tun0 ) works and copnnects fine.
Howewer when i try to terminate connection with "close" command
machine hangs ( no panic :-( ) .

>How-To-Repeat:

Connect using /usr/sbin/ppp to any site
and then try to terminate connection with "close"

>Fix:

 Donno, the problem is probably related to the latest changes
in if_tun.c ( support for lkm was added ).
Also i haven't seen this problem on kernel supped 3-4 days ago.
