>Description:
when I open a pptp tunel with net/mpd, my machine freezes (numlock does not respond, for instance).  I've compiled a new kernel without USB and SCSI/RAID controller support.

Here are the relevant configuration files:
/usr/local/etc/mpd/mpd.conf:

default:
        load vpn

vpn:
        new -i ng0 vpn vpn
        set iface disable on-demand
        set iface idle 0
# disconnect the client after 8 hours
        set iface session 28800
        #set iface route 192.168.2.0/24
        set bundle disable multilink
        set bundle authname my_username
        set bundle password my_password
        set link yes acfcomp protocomp
        set link no pap chap
        set link accept pap
        set link mtu 1460
# If remote machine is NT you need this..
#       set link enable no-orig-auth
        set link keep-alive 10 75
        set ipcp no vjcomp

/usr/local/etc/mpd/mpd.links:
vpn:
        set link type pptp
        set pptp self ZZZ
        set pptp peer YYY
        set pptp enable originate incoming outcall
        set pptp disable windowing


where:
   ZZZ my ethernet IP address
   YYY ip address of TCP peer

>How-To-Repeat:
run: 
when I type 'open' inside mpd shell, and after tunnel is UP, the machine freezes.

Closing the PR since this is not a problem (yet) . Advised to check the 
mailinglists and ask around and then head back to me if the issue is 
really a problem.

 Hello,
 
 Can you please contact the hackers (and/or the ports) mailinglist
 before submitting a problem report. Although you detail a lot of
 information (my appriciation for that!) it is good to run this through
 a couple
 of people on forehand to make sure this is a problem and not a local
 misconfiguration or in this case a port problem.  There might also be
 people that experienced this as well and got it solved already...
 
 Please have a look at
 http://lists.freebsd.org/mailman/listinfo/freebsd-hackers (change
 hackers into ports to get the proper mailinglist for the ports people).
 
 I will close the PR till you either file a new one, and/or contact me
 with the information you found after verifying this on the
 mailinglists.
 
 This is not to make you angry or something, but to make sure we use the
 resources the best we can and try to help you solve the problem much
 quicker.
 
 Thanks!

 Thanks for your prompt reply & for the pointer.  I am subscribing to
 freebsd-hackers ML.  I'll forward this issue there.

 I am happy to help in anyway I can.  But my gut feeling tells me that
 someone will end up reopening this again here sooner or later: a PC
 should not freeze for a user mode tool misconfiguration, am I right?
 
 I'll just forward this issue to the hackers ML.
