   Solution Type: Sun Alert
   Solution  238045 :   On Solaris 10 the "nxge" Driver for Specific
   Ethernet Cards May Report Excessive and Spurious Errors          
   Bug ID: 6572623, 6573600, 6623776, 6625536

   Product
   Solaris 10 Operating System

   Date of Resolved Release: 30-May-2008

   SA Document Body
   On Solaris 10 the "nxge" Driver for Specific Ethernet Cards May Report 
   Spurious Errors (see below for details)

   1. Impact

   Systems using the "nxge" ethernet driver for Dual 10 Gigabit Ethernet or 
   Quad Gigabit Ethernet adapters may be affected by continuous "nxge" 
   messages which hamper interactive work on the system console. This issue 
   also causes spurious "nxge fm" reports to fill the /var file system and 
   an over consumption of CPU resources.

   2. Contributing Factors

   This issue may occur in the following releases:
   SPARC Platform
     *
   Solaris 10 without patch 127111-08

   x86 Platform
     *
   Solaris 10 without patch 127112-08

   The following are Network Interface Cards which use the "nxge" ethernet 
   driver 
   :
   501-7606 X4447A-Z  Sun Multithreaded Quad GbE x8 PCIe Low Profile Adapter
   501-7765 X7287A-Z  Sun Multithreaded Quad GbE x8 PCIe ExpressModule
   501-7283 X1027A-Z  Sun Multithreaded 10 GbE Networking Card Low Profile Adapter
   501-7626 X1028A-Z  Sun Multithreaded 10 GbE Networking Card PCIe ExpressModule
   501-7489 SESX7XA1Z Sun Dual 10GbE XAUI Card
   The bundled package is SUNWnxge VERSION 11.10 and the unbundled package
   is SUNWnxge VERSION 1.0.
   The SUNWnxge package version can be obtained as follows:
        # pkginfo -l SUNWnxge | grep VERSION

   3. Symptoms

   One or several of the symptoms below may be observed.
   - Many nxge fma reports similar to the following:
    # fmdump -eVu c6fa7b94-218b-650d-91ac-8f2306cd0a53
    TIME                           CLASS
    Jan 14 2008 08:29:17.231163950 ereport.io.service.unaffected
    nvlist version: 0
       class = ereport.io.service.unaffected
       ena = 0x53b0bd901f400c01
       detector = (embedded nvlist)
       nvlist version: 0
               version = 0x0
               scheme = dev
               device-path = /pci@2,600000/network@0,3
       (end detector)
   - Many "nxge_syserr_intr: device error - ZCP" WARNINGS are logged.
   - Messages similar to the following interrupt the console:
   SUNW-MSG-ID: SUNOS-8000-1L, TYPE: Defect, VER: 1, SEVERITY: Minor
   EVENT-TIME: Mon Jan 14 14:44:15 PST 2008
   PLATFORM: SUNW,SPARC-Enterprise-T5220, CSN: -, HOSTNAME:
   SOURCE: eft, REV: 1.16
   EVENT-ID: 053667ce-ef6c-eb69-d25c-c4cd566e532b
   DESC: The EFT Diagnosis Engine encountered telemetry for which it is 
   unable to produce a diagnosis.  Refer to http://sun.com/msg/SUNOS-8000-1L 
   for more information.
   AUTO-RESPONSE: Error reports from the component will be logged for 
   examination by Sun.
   IMPACT: Automated diagnosis and response for these events will not occur.
   REC-ACTION: Run pkgchk -n SUNWfmd to ensure that fault management 
   software is installed properly. Contact Sun for support.

   4. Workaround

   There is no workaround. Please see Resolution section below.

   5. Resolution

   This issue is addressed in the following releases:
   SPARC Platform
     *
   Solaris 10 with patch 127111-08 or later

   x86 Platform
     *
   Solaris 10 with patch 127112-08 or later

   See patch README for patch requirements.

   NOTE:
   Special procedures are needed if using the unbundled version SUNWnxge 1.0.
   The unbundled version needs to be removed and the bundled version 
   installed.
   And then install the patches 127111-08 or 127112-08.
   If using the unbundled SUNWnxge 1.0 version follow the instructions in 
   the following product Release Notes.
