IZ69409: PCI ENHANCED ERROR RECOVERY DOES NOT SUCCESSFULLY COMPLETE APPLIES TO AIX 5300-09

APAR status

  • Closed as program error.


Error description

 

  • The 4-Port 10/100/1000 Base-TX PCI-X Ethernet adapter may
    intermittently fail to recover from PCI bus errors when
    installed in a 7311-D20 drawer.  The AIX error log may look
    similar to:

Problem conclusion

  • Modify adapter device driver to avoid reading adapter's
    PCI config space registers during EEH recovery procedure.
