This was resolved previously, the bug just wasn't updated. Current rev libcxgb3 is already in rhel6.
Red Hat Enterprise Linux 6.0 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you.
