First time reported here: https://bugzilla.redhat.com/show_bug.cgi?id=223631#c36 Andy had request to open another bug to track csum issue here: https://bugzilla.redhat.com/show_bug.cgi?id=223631#c57 Flavio This request was evaluated by Red Hat Product Management for inclusion, but this component is not scheduled to be updated in the current Red Hat Enterprise Linux release. If you would like this request to be reviewed for the next minor release, ask your support representative to set the next rhel-x.y flag to "?". Unfortunately the previous automated notification about the non-inclusion of this request in Red Hat Enterprise Linux 5.3 used the wrong text template. It should have read: this request has been reviewed by Product Management and is not planned for inclusion in the current minor release of Red Hat Enterprise Linux. If you would like this request to be reviewed for the next minor release, ask your support representative to set the next rhel-x.y flag to "?" or raise an exception. |

Additional info: * The problem is observed only in the bonding. * Disabling rx checksumming, the message goes away as it is expected.
