A colleague of mine has seen the exact same issue with Dell R610 systems running CentOS 5.x It looks like this might be the same issue as: <https://bugzilla.redhat.com/show_bug.cgi?id=520888> Which seems to suggest disabling MSI - i.e. load the bnx2 module with "disable_msi=1" We haven't tried this yet (as we went back to using CentOS 4 on these boxes - which works OK) James Pearson
