I've got a HP blade enclosure with a Nortel switch module, and one of the blades are running VMWare ESX. When I turn on this blade (or enable its switch port), the entire network stops working after a short while. Other server blades can no longer communicate, for instance. The only clue I've found so far is the following error message from one of the other blades that's running CentOS 5.4: [bnx2x_hw_stats_update:3701(eth0)]NIG timer max (426) The line is logged every two seconds and the number in parenthesis is incrementing each time. Once I disable the port to the ESX server, the network instantly recovers. I have no reason to believe the Linux kernel/bnx2x is doing anything wrong here, but I'm wondering if anybody has any idea on what this error message means and what could be causing it? I can't see anything unusual going on with tcpdump, and the error counters in "ip -s -s link show eth0" are all zero.
