Hi,
I have an ADSL line that uses PPPoE encapsulation. I've been trying to get
a PPTP connection working with FreeBSD 4.2 release on the same box that
connects to the ADSL.
The process is as follows:
1) Bring up PPPoE connection, using either user-space PPP or MPD. This part
works flawlessly using either method.
2) Bring up PPTP connection using MPD.
The result is always the same: Kernel panic in the next 30 seconds.
============
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x70
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc01a7dd0
stack pointer = 0x10:0xc0388328
frame pointer = 0x10:0xc038834c
code segment = base 0x0, limit 0xfffff, type 0x1b
= dpl 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, iopl = 0
current process = idle
interrupt mask = net tty bio cam
trap number 12
panic: page fault
============
Can anyone help? I would be willing to help with debugging this, but I'm
not a kernel hacker, and I really don't know where to start. I have log
files, etc, but I didn't want to post that much stuff here.
