I also get such BUG messages when I try to use OpenMPI over Infiniband and 
mpirun dies.
Same with:
- OFED-1.5.3.2 and linux-2.6.39.4 vanilla
- OFED-1.5.3.2 and linux-2.6.38

I've tried a rather old kernel, too. I get same BUG messages with:
- OFED-1.5.3.2 and linux-2.6.29 vanilla
- linux-2.6.39.4 vanilla (with the included Infiniband modules - not the modules from OFED)

That's the whole conversation:
