>Description:
I'm using T-DSL (by the german Telekom) with FBSD 4.3. Mostly 
everything is fine. BUT sometimes whenn I log in as root, call ppp and
enter dial, the system freezes.

Here the last ouput on my screen:

--< snip >--
Fatal trap 12: page fault while in kernel mode
fault virtual address      = 0x4
fault code                 = supervisor write, page not present
instruction pointer        = 0x8:0xc24fa3b
stack pointer              = 0x10:0xd1d1c98
frame pointer              = 0x10:0xd1d1cc8
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            = 208 (ppp)
interrupt mask             = net tty
trap number                = 12
panic: page fault

--< snap >--

Here is the last output of ppp from the logfile (with out time and 
date):

--< snip >---

Phase: Using interface tun0
Phase: deflink: Created in closed state
Phase: PPP Started (interactive mode)
Phase: bundle: Establish
Phase: deflink: closed -> opening

--< snap >---
>How-To-Repeat:
As I have described it above.
