ASR9K RSP440 to RSP880 migration impacted SIP-700 traffic

We upgraded an operating ASR 9010 running 5.3.4sp4 from RSP440-TRs to RSP880-TR-RL following the instructions here.

 

Everything was going as expected with no noticeable impacts on traffic. However, at some point in the process the TDM circuits attached to the Channelized OC3 adapter (SPA-1CHSTM1/OC3V2) in our SIP-700 card started dropping traffic. Every T1 connection would drop approximately half of the pings, though routing was stable.

 

After completing the procedure, we physically removed and reset the fiber connection to the OC3 module to no affect. Reloading the CPU on the SIP-700 card did fix the issue.

 

Before we push this card upgrade across the fleet, I'd like to know if this is a known bug or is there something we missed in following the procedure?

 

Thank you.
