The following is console output immediately before a panic on a system
running lustre with OFED 1.1.  How can I find out what it
means?

...shortly before it happens, the lustre/lnet OFED driver receives a
number of what I believe to be duplicate SEND completion
events.  It seems quite sporadic, and doesn't appear to track hardware.
