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] ipconfig:ip_auto_config:1417: IP-Config: Entered. That line is printed before the delay. There are no other new debug lines from ipconfig.c. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1259861 Title: 5-10 second delay in kernel boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1259861/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
