Most of the log messages above come from ahd_dump_card_state() in "aic7xxx" SCSI driver. The aic79xx driver is called to process an interrupt. The driver determines it is a PCI error (in ahd_pci_intr). ahd_pci_intr prints "PCI error Interrupt", then dumps the state of the HBA. (This is an extremely verbose output that the driver dumps routinely. It is useless to anyone other than an aic79xx firmware/hardware expert). Next, ahd_pci_intr determines that the error type is "Address or Write Phase Parity Error Detected" and the "pci_status_source" is TARG. As far as I can tell, TARG is a reference to a SCSI target. This is relevant because you (and the reporter in bug 140311) do not have any SCSI targets attached. This is apparently just noise caused by the fact that there is no attached SCSI bus. It would be ideal for us to determine the source of this and stop it, but as far as I can see, it is not a critical or dangerous situation. This bug is filed against RHEL 3, which is in maintenance phase. During the maintenance phase, only security errata and select mission critical bug fixes will be released for enterprise products. Since this bug does not meet that criteria, it is now being closed. For more information of the RHEL errata support policy, please visit: http://www.redhat.com/security/updates/errata/ If you feel this bug is indeed mission critical, please contact your support representative. You may be asked to provide detailed information on how this bug is affecting you. |
