Hi Guillaume,

There is a workaround for this issue in the /etc/init.d/openibd script (which loads OFED drivers upon boot).

You can increase the value of NODE_DESC_TIME_BEFORE_UPDATE parameter in the /etc/infiniband/openib.conf file to postpone the node description field update:

# Wait for NODE_DESC_TIME_BEFORE_UPDATE sec before node_desc update

NODE_DESC_TIME_BEFORE_UPDATE=10

Regards,

Vladimir
