[rhelv6-list] bnx2 intermittent error

[Bryan Hepworth]

Hi Everyone

I have an intermittent Ethernet failure on one of my machines and was wondering if anyone had bumped up against a similar issue.

The machine is a Dell R715 I have two that are almost identical but only see this problem on one box.
