PPPoE create bba subblock failed

Trying to issue the pppoe enable command on a fastethernet port on my 1841, and continually get this error message:

PPPoE create bba subblock failed.

What does it mean? I can't find ANYTHING on Cisco's site, or even google on it.

PPPoE will be for an ADSL connection.

Whatever information you guys can help with would be greatly appreciated.

In the config here, I still have the BVI enabled - since I'm still trying to connect to my ISP via my Wic-1ADSL... But since I was having issues, I tried to just go through the ethernet port - to my isp provided modem...

And that's when I get the pppoe create subblock failed.

Even after I completely delete all the config under the Ethernet ports.
