If you are using VMware ESX or ESXi 4.1 with the Broadcom bnx2x (in-box driver version 1.54.1.v41.1-1vmw), you may experience some of these symptoms:

  • A loss of network connectivity from the host
  • A purple diagnostic screen occurs
  • The bnx2x driver or firmware panics and dumps a backtrace, following these messages in the /var/log/vmkernel (ESX) or /var/log/messages (ESXi) log file:

Note: This issue has occurred with, but is not exclusive to HP Proliant and Integrity blade servers with BCM57711E network interfaces.


This issue is resolved in a patch release for ESX/ESXi 4.1. For more information, see:

This issue is also resolved in the asynchronous Broadcom driver release bnx2x 1.60.50.v40.3 and newer. For more information, see VMware ESX/ESXi 4.0 Driver CD for Broadcom NetXtreme II BCM57710, BCM57711, BCM57711E Ethernet Controller and How to install async drivers on ESX/ESXi 4.x (1032936).

This issue is also seen with the 4.1 U3 inbox driver version 1.54.1.v41.1-2vmw. See, Download VMware ESX/ESXi 4.x Driver CD and HP Download drivers and software.

Additional Information

To determine the version of the installed driver:

  1. Open a console to the ESX or ESXi host. For more information, see Unable to connect to an ESX host using Secure Shell (SSH) (1003807) or Using Tech Support Mode in ESXi 4.1 (1017910).

  2. Determine the version of the bnx2x driver using the command:

    vmkload_mod -s bnx2x | grep Version

Note: If this command returns no version number, the bnx2x driver is not in use on the ESX/ESXi server and this issue is not applicable.
