+++ This bug was initially created as a clone of Bug #206223 +++ The default 50-udev.rules file includes the following lines: KERNEL=="umad*", NAME="infiniband/%k", MODE="0660" KERNEL=="issm*", NAME="infiniband/%k", MODE="0660" KERNEL=="uverbs*", NAME="infiniband/%k", MODE="0660" KERNEL=="ucm*", NAME="infiniband/%k", MODE="0660" KERNEL=="rdma_cm", NAME="infiniband/%k", MODE="0660" The Infiniband support now requires the openib base module for any of the other user space components to work, and that rpm contains the file 90-openib.rules that has the authoritative list of rules that are needed to work with our shipping Infiniband support. The duplicate rules should be removed from udev, especially since there are some with incorrect permissions, which implies that the rules need fixed anyway, so might as well just leave them out and let the openib rules file be authoritative.
finally :)
