I installed a vanilla 4.5 kernel, which has this debug logging change: https://git.kernel.org/cgit/linux/kernel/git/stable/linux- stable.git/commit/net/ipv4/ipconfig.c?id=09605cc12c07830659a19b266503795c511a2060 After booting with the dyndbg argument, the only new output is this: [1.079405]

2016-03-19 Thread Richard Hansen
After studying the code in net/ipv4/ipconfig.c I'm fairly confident that the problem is caused by wait_for_devices() failing to find any network interfaces and timing out. That function waits for 12 seconds before giving up, and the time difference between the "IP-Config: Entered" message and the

Yes, I think the change to CONFIG_IP_PNP=y is what caused this problem. If you look in net/ipv4/Makefile, you'll see this line: obj-$(CONFIG_IP_PNP) += ipconfig.o If CONFIG_IP_PNP is not set to y, then all of net/ipv4/ipconfig.c is excluded from the resulting kernel. That file contains the c

I have been seeing this on multiple machines since trusty (at least). I'm currently running wily. I noticed that if I remove the 'ip=dhcp' kernel command line parameter then the 10 second delay goes away. (I added ip=dhcp so that I could ssh into the initramfs to unlock the encrypted root device
