[openib-general] ehca weirdness??

[Troy Benjegerdes]

I just built a fresh 2.6.16 kernel, and the ehca (and associated ibverbs
stuff) from the lastest stubversion (5988), and things like
'ibv_devices' fail..

p5l3:~# ibv_devices
libibverbs: Warning: no userspace device-specific driver found for
uverbs0
        driver search path: /usr/lib/infiniband
    device                 node GUID
    ------              ----------------


strace seems to indicate it can't find a 'vendor' file for the device in
sysfs?
