Cause
此问题已在 2025 年 8 月 14 日发布的固件版本 32.46.3048 中得到确认并得到解决。
这是一个已知的 NVIDIA 问题。在 PCIe 网络初始化期间,设备固件影响了训练过程,此问题已从固件版本 32.46.3048 开始得到解决。
固件算法经过优化,可提高 PCIe 链路稳定性。经确认,新发货的 NVIDIA 显卡已经包含更新的固件版本 32.46.3048 或更高版本。
Resolution
运行完整的电源重启以验证是否再次可检测到卡。
- 如果重启电源后故障卡恢复:
将 BlueField-3 固件更新到 v32.46.3048 或更高版本,并确保 BFB 映像与更新的固件对齐。您可以使用 NVIDIA DOCA Software Framework:
