Ubuntu and OFED package

   I'm having an issue with using the available distro OFED package.  
This was with Ubuntu 9.04:

node:~$ sudo ibv_devinfo
mlx4: There is a mismatch between the kernel and the userspace  
libraries: Kernel does not support XRC. Exiting.
Failed to open device

    This was using the 2.6.28-11-server kernel. We also tried backing  
down to a 2.6.27-15-server kernel and got a similar error.

   Can anyone give me a hint on what to do? Or do i need to scrap the  
ubuntu provided package?

thanks,
kevin

Has libmlx4 been installed ?

Bart,

   It appears that it has.

node:~$ aptitude search libmlx4
i A libmlx4-1                       - A userspace driver for Mellanox  
ConnectX I
p   libmlx4-1-dbg                   - Debugging symbols for the  
libmlx4 driver
p   libmlx4-dev                     - Development files for the  
libmlx4 driver

It seems you are using the default Ubuntu kernel but a libmlx4 package
from somewhere else.  If you are using the OFED-patched libmlx4 you will
need to use the OFED-patched kernel too.

   I agree. I guess i was asking specifically if someone knew what the  
correct ubuntu magic was. There is a single ubuntu "ofed" package. I  
don't find any reference to a special ubuntu kernel version for use  
with ofed.

thanks,
kevin
