It doesn't happen on every machine; but if I can, I'll try an add some printk's and test it.

Shubhadip,

Let me know the next time you see this. We may have to build a release that has extra diagnostics in rdma_accept() to figure this out.

The rdma_cm will return EINVAL if the cm_id state is invalid.  You could add a
printk in rdma_accept() in cma.c to see if this is the case.  It could also come
from an error trying to modify the QP state if the conn_param values are
incorrect.
