Hi,

I have tried the kernel 2.6.11 drivers on an x86-64 machine with a
MT23108 card. The driver loads ok after
$ modprobe ib_mthca; modprobe ib_umad

Since I use devfs, I have to manually create

$ mknod /dev/infiniband/umad0 c 231 0
$ mknod /dev/infiniband/umad1 c 231 1
$ mknod /dev/infiniband/issm0 c 231 64
$ mknod /dev/infiniband/issm1 c 231 65

I get 

$ /usr/local/ib/bin/ibstat
CA 'mthca0'
        CA type: MT23108
        Number of ports: 2
        Firmware version: 3.2.0
        Hardware version: a1
        Node GUID: 0x000000008815bcaa
        System image GUID: 0x000000008815bcaa
        Port 1:
                State: Initializing
                Physical state: LinkUp
                Rate: 10
                Base lid: 0
                LMC: 0
                SM lid: 0
                Capability mask: 0x00500a68
                Port GUID: 0x0000000000000000
        Port 2:
                State: Down
                Physical state: Polling
                Rate: 2
                Base lid: 0
                LMC: 0
                SM lid: 0
                Capability mask: 0x00500a68
                Port GUID: 0x0000000000000000

which already looks strange (GUID 0 ???). Running opensm then doesn't
activate the ports:

Apr 05 19:18:25 [4000] -> OpenSM Rev:openib-1.0.0
Apr 05 19:18:25 [4000] -> osm_opensm_init: Forcing single threaded dispatcher.

What could have gone wrong?
