No error

Additional info:

Server is a dell poweredge 2950, with embedded bnx2 card.

I have also tried to compile last bnx 2.2.4d driver, same error

Comment 2 Alexandre Derumier 2013-12-20 14:48:15 UTC

Hi,

some news :

The problem is coming from dell openmanage (7.1). I have remove it, and now it's working fine.

(I found some old similar bug with openmanage and bnx2 on the net)

You can close the bug.
