I posted this question over a week ago to the freebsd-questions list but
didn't get any help/feedback yet.  Sorry if the question is a bit basic
for the gurus.  I am just looking for a place to start searching.

Thanks,
Dany

Greetings,
  I recently got my hands on an old DEC pentium 133 PC.  I just got
FreeBSD 3.4-RELEASE installed.  I am interested in getting PPPoE
running.  I recompile a kernel with all the NETGRAPH options.  The first
problem I noticed is a 50% success rate on getting a successful
connection.  I start my session with the command "ppp -dedicated".  I
stop the session with "kill <PPP PID>".  When the process terminates,
I get the following 2 messages:

/var/log/messages:
Jan 12 16:48:19 freebsd ppp[265]: tun0: Warning: deflink: Oops: Got 8
bytes but 4 byte payload
Jan 12 16:48:20 freebsd ppp[265]: tun0: Warning: deflink: Oops: Got 8
bytes but 4 byte payload

When I try to restart "ppp -dedicated" I don't get any special error
messages but a tcpdump suggests that nothing goes out on the Ethernet
interface.  I kill the ppp process and re-issue the command "ppp
-dedicated" and everything works!  I wanted to do more debugging today
but now nothing works.  I am getting a write error on the tun
interface.   Any idea on what extra debugging I could turn on...

Here is my configuration, the output on /var/log/ppp.log for the write
failure and finally output from a successful session:
/etc/ppp/ppp.conf

default:
 set device PPPoE:de0
 set MRU 1490
 set MTU 1490
 set authname user@domain.com
 set authkey password
 set log Phase Chat LCP IPCP CCP tun command
# set log Phase IPCP CCP tun LCP
 set dial
 set login "TIMEOUT 1.5 name:\\r-login:\\U:\\P ocol:PPP HELLO"
 set ifaddr 10.0.0.1/0 10.0.0.2/0
 add default HISADDR
# enable dns
 set cd off
 set crtscts off
