Hi all,

Not yet; if you want to have a crack at it there are some very-basic notes on 
what to do here:

The 1.4.2 ofa-kernel package is useless for sid users.

The best person to talk to about merging XRC is Roland Dreier. He is the 
maintainer of the debian libibverbs package, and the upstream kernel maintainer 
for the infiniband drivers.

Is the XRC stuff really required by openMPI/mpich, or are the errors that get 
generated at runtime just  generic errors caused by the mismatched 
kernel/libibverbs packages?

I notice that SID has openmpi packages that contain the openib btl, so openmpi 
obviously compiles on systems without XRC support. Has anyone tried the SID 
openmpi packages?
