I just wanted to chime in and report that I too am seeing this error with  
MVAPICH 0.9.7 and the SilverStorm 3.2.0.0.25 drivers.

I'm heartened with the progress towards the 2nd generation OpenIB stack,  
but sometimes it's not an option.

Interestingly enough, SilverStorm seems to distribute their own branch of  
MVAPICH (albeit an older one).  Binaries compiled with the semi-functional  
MVAPICH (ie using SilverStorm drivers & libs) will run fine on the  
SilverStorm branch of MVAPICH.  (Running SS MVAPICH-combiled binaries on  
MVAPICH 0.9.7 results in the same error as reported above.)

I've also verified that I'm not running into a case of mixed libraries  
 from MVAPICH and SilverStorm's MPI.  (Start with a fresh OS install, then  
install the OS & MPI, test, wipe the system, start over.)
