We were patching one of our ESXi hosts - it is a Dell FC630 inside a Dell FX2 chassis - w/ QLogic / Broadcom BCM57840 NICs. We were patching from 5.5 build 2068190 to the latest - 2718055.
after patching, ESX no longer sees any network adapters. And since I can't connect to the machine at all (and no more ESX shell from the console) i can't attempt to install a new version of a driver.
anyone run into this, have any advice?
