    Forerunner CRC error on 54SG/53SG3 triggers watchdog timeout crash
    CSCtk75675
     
    Description
    Symptom:
    Switch can crash with an Watchdog NMI Vector 000 and CRC error.

    Conditions:

    1) Applies to Sup6-E, 4900M, Sup6L-E, 4948-E
    2) IOS 12.2(50)SG OR 12.2(53)SG3 OR 12.2(54)SG only
    3) "%C4K_SUPERVISOR-2-FPGASOFTERROR: Memory inconsistency detected" have
    appeared on the switch followed by link flaps and pluggable insertion/removal on uplinks
    4) On 4900M affected ports are baseboard ports
    5) On 4948-E affected ports are all ports

    Workaround:
    1) Reload the switch as soon as "%C4K_SUPERVISOR-2-FPGASOFTERROR: Memory
    inconsistency detected" messages appear.

    2) Upgrade to 12.2(54)SG1 OR 12.2(53)SG4 (and higher) OR 15.0(02)SG (and
    higher)

    Further Problem Description:
    "%C4K_SUPERVISOR-2-FPGASOFTERROR: Memory inconsistency detected" is due to a
    legitimate parity error occurring on a device on the supervisor. The switch
    should be reloaded at the next available maintenance window.
