[c-nsp] Failed ADSL retrains on 1801 + >15.1(1)T

[Peter Hicks]

All,

I have a Cisco 1801 with an ADSL2+ circuit in to ATM0 and PPPoE.

With IOSes later than 15.1(1)T, the ADSL interface refuses to retrain
and a 'debug atm errors' gives:

*Sep 10 21:57:48.821: (atm_vc_is_bridged_dot1q)ATM: VC with handle 0x0
not found
*Sep 10 21:57:48.821: VC micro block get: Invalid vc handle
*Sep 10 21:57:53.337: DSL(ATM0): No retrain. sleep 20 seconds

Has anyone else experienced the same problem?  15.1(1)T is fine,
anything later throws up this behaviour.
