  • NIC card BCM5720 randomly stops receiving packets

    Posted on

    Dear community guys,

    DELL server R640
    Redaht 7.3 ( maipo )
    NIC card : BCM5720 ( 4 ports )

    Issue:
    Randomly NIC stop receiving packets.
    No error messages in dmesg and syslog
    Only errors reported by the DELL server:

    A fatal error was detected on a component at bus 23 device 0 function 1.
    
    23=0x17
    

    which points actually to the NIC card according to lspci

    17:00.1 Ethernet controller: Broadcom Limited NetXtreme BCM5720 Gigabit Ethernet PCIe
    

    The issue is very similar to the Redhat Verified Solution:
    https://access.redhat.com/solutions/26765

    As per DELL Support I have applied the last firmware ( 20.6.58).
    As I don't have a RedHat Support I am thinking about disabling the MSI-X feature.

    Let me know your thoughts.

    Many thanks.

    JJ.
