CentOS networking BNX2
Having some trouble with my NICs. The server starts fine and I can wget/ping etc. However, when I /etc/init.d/networking restart I then receive the following error:
Bringing up interface eth0: bnx2: fw sync timeout, reset code = 1030009
SIOCSIFFLAGS: Device or resource busy
Consequently, the task fails. I have searched around on google users suggesting to disable PNP in the BIOS but I see no option. Here is some system information:
$ ethtool -i eth0

Any help would be appreciated as I am at a loss.
It's possible you're hitting one (or both) of these bugs:
- https://bugzilla.redhat.com/show_bug.cgi?id=680411
- https://bugzilla.redhat.com/show_bug.cgi?id=693542

I have been having some issues with these bnx2 based cards. A fix for me was blacklisting the bnx2i module (this one does iSCSI offloading). If you don't need iSCSI offloading, try unloading bnx2i and blacklisting it in modprobe.conf.
