Under sys/class/infiniband, there's anohter folder named 'mthca0'; the
folder itself is also far from empty; containing things like the board_id,
firmware version fw_ver, etc.

Everything is fine.... Except for that one little omission:

KERNEL="umad*", NAME="infiniband/%k"
KERNEL="issm*", NAME="infiniband/%k"
KERNEL="uverbs*", NAME="infiniband/%k", MODE="0666"
KERNEL="ucm", NAME="infiniband/%k", MODE="0666"

in my udev configuration.

So now I'll go pound on it.
