There was a compilation problem that you fixed (Yes, it was my fault - I just discovered it a minute after the code was applied). 2. When you're using SR-IOV, during initialization, you get a CQE error with syndrome 0x2 on one of the probed VF's. 3. Regarding the BlueFlame - I don't see how it is related to the issue that you see. But it is a very easy experiment. Issue: "ethtool --set-priv-flags eth1 blueflame off" Please send me the module parameters you used when loading mlx4_core, a full dmesg with both mlx4_core and mlx4_en loading. Amir.
