I'm sorry we didn't respond to this earlier.
Have you seen a similar hang again? If so, which version are you
running now ("uname -v" will show this)? Can you send a fresh log,
including all the BUG and WARN messages?

Based on this warning message, I suspect this may be a bug in the
Mellanox network drivers you were using, which are not part of this
package. But the network hang might be a symptom of an earlier
failure.
Are you able to use the in-tree drivers for this hardware?
