[cisco-bba] strange dsl/pppoa disconnect

[Anastassios Chatzithomaoglou]

The following are some debug logs from a dsl customer getting strange disconnects.

Although the acct record shows "lost-carrier" which i suppose means telco/copper problem, 
i still can't understand the first line which shows a LCP incoming packet.

Any idea what might be happening?
