On one of our test clusters, I'm seeing a situation where multicast traffic is
not received on the QP which sends a message. All nodes that I actually tested
on the cluster have this problem (5 of 15). The devinfo from one of these is
below:
hca_id: mlx4_0
transport: InfiniBand (0)
fw_ver: 2.7.000
node_guid: 0002:c903:0002:5e0a
sys_image_guid: 0002:c903:0002:5e0d
vendor_id: 0x02c9
vendor_part_id: 26428
hw_ver: 0xA0
board_id: MT_04E0120005
The cluster is running OFED 1.5.2, with updated versions of ibacm and
librdmacm. (I updated those trying to debug this issue.) I do not see this
problem on my test systems (running 2.6.36).
I do see the same failure on separate set of test systems running 1.5.2, but I
don't know that the OFED version is the problem.
