I'm running on rhel4u6 with the 1.4.1 nightly from last night and
sometimes /dev/infiniband/rdma_cm is not created. I can see its entry
in /etc/udev/rules.d/90-ib.rules:
KERNEL="umad*", NAME="infiniband/%k"
KERNEL="issm*", NAME="infiniband/%k"
KERNEL="ucm*", NAME="infiniband/%k", MODE="0666"
KERNEL="uverbs*", NAME="infiniband/%k", MODE="0666"
KERNEL="ucma", NAME="infiniband/%k", MODE="0666"
KERNEL="rdma_cm", NAME="infiniband/%k", MODE="0666"
But only some of these are created:

I have both an IB HCA and an iWARP RNIC in this server:

I don't see any obvious errors occurring in syslog or dmesg.
What could cause this failure?
