Table 1-2 Table 1-3 FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 PHNE_17285 Symptom 7. The 'Operation Status' of the EISA FDDI interface, as displayed by the lanadmin(1M) command, is not marked 'down' when there is a cable disconnect. Defect 7. The ifOper MIB variable, that is displayed as the 'Operation Status' by the lanadmin(1M) command, shows the operational state of the interface. The EISA FDDI driver did not update the value of ifOper to 'down' when it detected a cable disconnect. PHNE_17061 Symptom Defect 1. The system panics with a data page fault when many Input/Output (I/O) cards are configured on a system with EISA FDDI card/driver. 2. NFS server daemons operating over EISA FDDI hang, eventually followed by a system hang. 1. When multiple I/O cards are configured it is possible that the driver's attempt t map its I/O buffer fails. Under these conditions, when the driver attempts to unmap these I/O buffers, the system panics with a data page fault. 2. When the driver fails to enqueue packets for transmission (as was seen under heavy NFS traffic), the driver treats these packets as dropped. However, it failed to free the buffers for the packet. this resulted in kernel memory leak, eventually leading to a system hang. Chapter 1 17
