I can confirm this. I saw the very same on i386. In my case, the VLAN is only used internally on my LAN, and I wanted to make it work again quickly, so I just removed the VLAN from the setup and used the hardware interface directly as pppoedev for pppoe0, which made it work again. I see that only as temporary workaround though. > I set the 'debug' flag for pppoe0 so I could see what happened: > pppoe(8863) state=1, session=0x0 output -> ff:ff:ff:ff:ff:ff, len=18 > pppoe(8863) state=2, session=0x0 output -> aa:aa:aa:aa:aa:aa, len=42 > pppoe0: timeout > [...] > aa:aa:aa:aa:aa:aa is a MAC I do not know. > > To further check for errors, I booted a working 5.4 installation and > used tcpdump on vlan10 before restarting the pppoe interface. > As expected, I get only one PADO after sending the PADI. > This PADO is received from a well known MAC. > > From here on, everything just works using the 5.4 installation. > On 5.5, until this point (PADI sent/PADO received) there is no > difference. > > For 5.4, the PADR is sent to MAC which sent PADO. > For 5.5, the PADR is sent to some other MAC I do not know. > There was neither a PADO sent from that MAC nor is there any other > occurence of that MAC in the tcpdump besides being target of PADR. > > In both installations, the PADO is sent from the same MAC. > Service-Name, AC-Cookie and Host-Uniq do match. > > Interestingly, the PADR to the unknown MAC includes the same AC-Cookie. > > I do not know how to proceed from here on, so I would be glad to get > some advice. > > Best Regards, > > Thorsten Bonck
