>Description:
   I tried today to setup an pppoe server on 5.x the first time.
I copied over my working configuration from 4.9 and started the 
mpd. Than a didn't two times an connection attempted from an
winxp an got two the same panic:

Feb 13 15:40:49 neo kernel: 
Feb 13 15:40:49 neo kernel: 
Feb 13 15:40:49 neo kernel: Fatal trap 12: page fault while in kernel mode
Feb 13 15:40:49 neo kernel: cpuid = 0; apic id = 00
Feb 13 15:40:49 neo kernel: fault virtual address	= 0x1c
Feb 13 15:40:49 neo kernel: fault code		= supervisor write, page not present
Feb 13 15:40:49 neo kernel: instruction pointer	= 0x8:0xc061b6d5
Feb 13 15:40:49 neo kernel: stack pointer	        = 0x10:0xd77e77a4
Feb 13 15:40:49 neo kernel: frame pointer	        = 0x10:0xd77e77b4
Feb 13 15:40:49 neo kernel: code segment		= base 0x0, limit 0xfffff, type 0x1b
Feb 13 15:40:49 neo kernel: = DPL 0, pres 1, def32 1, gran 1
Feb 13 15:40:49 neo kernel: processor eflags	= interrupt enabled, resume, IOPL = 0
Feb 13 15:40:49 neo kernel: current process		= 37 (swi1: net)
Feb 13 15:40:49 neo kernel: trap number		= 12
Feb 13 15:40:49 neo kernel: panic: page fault
Feb 13 15:40:49 neo kernel: cpuid = 0; 
Feb 13 15:40:49 neo kernel: 

So I'm very sad about. If you need more help to track down
the problem feel free to contact me.
>How-To-Repeat:
      Reboot the System and make an new connection attempt.

Responsible-Changed-Why:  
I believe the crash is not PPPoE specific. netgraph(4) sometimes panics 
when you ask to create node of unknown type trying to kldload the node 
module. 
I'm planning to fix this.

   Meho,
 
   can you please try to reproduce this problem on CURRENT
 newer than 30 May 2004? Make sure that ng_pppoe.ko and ng_tee.ko
 are loaded before running mpd.
