VMware ESX/ESXi 4.1 host with Broadcom bnx2x (in-box driver version 1.54.1.v41.1-1vmw) experiences a loss of network connectivity and a purple diagnostic screen:
We have not experienced this and we are using the 1.54 driver (it replaced the 1.48 driver when we did the vSphere 4.1 upgrade).
I called VMware tech support today, and they will have a 1.6x driver out 2nd week of November which should address this and other issues.
Vmware tech I spoke to said use the 1.6 driver and not the older 1.48 driver.
We still have a open ticket because we are not getting any networking performance info in vCenter using the 1.54 driver.
