Paul,


  [Kernel-packages] [Bug 1652348] [NEW] initrd dhcp fails / ignores
  valid response
  <https://www.mail-archive.com/search?<email address hidden>&q=subject:%22%5C%5BKernel%5C-packages%5C%5D+%5C%5BBug+1652348%5C%5D+%5C%5BNEW%5C%5D+initrd+dhcp+fails+%5C%2F+ignores%09valid+response%22&o=newest>

I also have this bug

IP-Config: no response after 2 secs - giving up
IP-Config: ens2f0 hardware address 90:e2:ba:d1:36:38 mtu 1500 DHCP RARP
etc., etc., etc. ...

and tracked it to:

c

I set the countdown to "2 3 4 6 9" and saw the count of failures match 
appropriately.

I note that there are no problems if I attach an Ethernet cable from my 
router to the PC. A probable solution is to use wlan (to get a 
connectible device) or to test and see if the eth actually has a 
connected cable. Perhaps both.
