Hi Sean,
Resolving this issue is critical for us since it prevent us from any 
usage of the new multicsat module.
An easy way to reproduce it is to use the OFED "openibd" script. Just 
run "openibd start" and than "openibd stop" and you will see the 
problem. This script is available within OFED release.

Thanks,
