The issue has been confirmed and was resolved in firmware version 32.46.3048, released on August 14, 2025. This is a known NVIDIA issue. The device firmware impacted the training process during PCIe network initialization, and the matter has been resolved starting from firmware version 32.46.3048 . The firmware algorithm has been optimized to improve PCIe link stability. It is confirmed that newly shipped NVIDIA cards already include the updated firmware version 32.46.3048 or later .
Run a full power cycle to verify whether the card becomes detectable again. If the failed card recovers after the power cycle: Update the BlueField‑3 firmware to v32.46.3048 or later , and ensure that the BFB image is aligned with the updated firmware . You can download the appropriate files using the NVIDIA DOCA Software Framework : https://developer.nvidia.com/doca-downloads?deployment_platform=BlueField&deployment_package=BF-FW-Bundle&installer_type=BFB If the card remains undetectable after the power cycle: Proceed with opening a service request for a replacement card to resolve the issue.
