Description Ash Westbrook 2016-08-09 14:31:10 UTC
Description of problem:

When the RHEL kernel loads up, it takes ~30-50 seconds to "come up" during the boot process.  During this time, the system acts like the cable is disconnected.  (I believe there was a "no carrier signal detected" message from tg3 over the system console)

The card eventually comes up and works great (full Gigabit speed, no dropped packets as far as I can tell).  Our problem is that in the ~30-50 second delay, Red Hat's kickstart retrieval times out and dumps us to an emergency dracut prompt.  Once at the prompt, I can use dhclient to acquire an IP address and get on the network, but cannot continue our kickstart install.

Version-Release number of selected component (if applicable):

RHEL 7.2

How reproducible:

Always (whether dhcp or static)

Steps to Reproduce:
1. Reboot server and wait for pxe
2. System drops into emergency mode 

Actual results:

System drops into emergency mode 

Expected results:

System should provision as expected
