>Description:


When creating an IPv6 tunnel using gif0(freenet6 provider) , before xfce4-panel has started, results in a kernel panic.  As well kill -HUP panel_PID while the gif0 tunnel is up. All panics look the same:

Jan 15 19:36:44 fortytwo /kernel: Fatal trap 12: page fault while in kernel mode
Jan 15 19:36:44 fortytwo /kernel: fault virtual address = 0x5c
Jan 15 19:36:44 fortytwo /kernel: fault code            = supervisor read, page not present
Jan 15 19:36:44 fortytwo /kernel: instruction pointer   = 0x8:0xc01cf83f
Jan 15 19:36:44 fortytwo /kernel: stack pointer         = 0x10:0xd5c0cd58
Jan 15 19:36:44 fortytwo /kernel: frame pointer         = 0x10:0xd5c0ce2c
Jan 15 19:36:44 fortytwo /kernel: code segment          = base 0x0, limit 0xfffff, type 0x1b
Jan 15 19:36:44 fortytwo /kernel: = DPL 0, pres 1, def32 1, gran 1
Jan 15 19:36:44 fortytwo /kernel: processor eflags      = interrupt enabled, resume, IOPL = 0
Jan 15 19:36:44 fortytwo /kernel: current process               = 18164 (xfce4-panel)
Jan 15 19:36:44 fortytwo /kernel: interrupt mask                = tty
Jan 15 19:36:44 fortytwo /kernel: trap number           = 12
Jan 15 19:36:44 fortytwo /kernel: panic: page fault

Only numbers that change are stack pointer and current process number.


>How-To-Repeat:


creat gif0 tunnel then start xfce4 as user with xfce4-panel and xfce4-session.  OR  HUP xfce4-panel after gifo is up and runnig


>Fix:


workaround for now, start xfce4 (panel and session manager) first, then bring up IPv6 tunnel.

Fix, I don't know, sorry.

Responsible-Changed-Why:  
This really sounds to me like a kernel bug that the port is tickling, 
rather than a ports bugs, so reassign it to kern.

 Please see
 
   http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html
 
 for instructions on how to obtain useful data from a panic.
 
 Also, please wrap your emails at 70 characters so they may be easily read.
