>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.
