Symptoms
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:
