Could you try to configure "speed nonegotiate" under the port-config?
See the following in the "hardware limitations" portion of the release notes:
"The following limitations apply to Cisco QSA Module (CVR-QSFP-SFP10G) when Cisco 1000Base-T Copper SFP (GLC-T) or Cisco 1G Fiber SFP Module for Multimode Fiber are plugged into the QSA module:
- 1G Fiber modules over QSA do not support autonegotiation. Auto-negotiation should be disabled on the far-end devices."
