Hi,
I am currently experiencing some trouble with my connectx2 cards.
I have been doing test with smallish server without any problem and this week
I upgraded to a more beefier option. However I fail to be able setup the IB
card with our current kernel .
The servers spec are as follow:
* 4x 10 core Intel(R) Xeon(R) CPU E7- 4870 @ 2.40GHz stepping 02
* 1TB of RAM
* 1 connectx2 IB
Kernel Version : 3.5.0
Note if I downgrade to a 3.2 kernel I do not experience this issue. However I
am forced to work with a 3.5 or higher. Can somebody help me with that?
Thanks
Benoit
