[ewg] Crash in iw_cxgb3 (Chelsio) in OFED 1.4.1

[pandit ib]

Steve,

This problem happens on OFED 1.4.2 as well. support at chelsio.com also
suggested upgrading to 1.4.2.
We are running our application (non MPI based).
Under reasonable load we get this crash.

Any ideas what might cause the NIC to be unresponsive?
In this case looks like the CQ is having problems?

Ranjit
