Issue

When network interfaces are brought online during boot, the system hangs while bringing up eth0/em1 or similar. The following messages are printed to the console:

be2net 0000:04:00.0: Error in Card Detected! Cannot issue commands
be2net 0000:04:00.0: Error in Card Detected! Cannot issue commands

The console may then show a hung task, blocked for more than 120 seconds. The call trace is:
