@rhansen, your bug might be a different one, since ip=dhcp is processed by the initramfs, while I'm talking about the kernel, before the initramfs gets to run.
The bug is still there in Xenial. I noticed that it doesn't happen in all hardware; I've seen it in *some* real clients and under VirtualBox, while I haven't been able to reproduce it under KVM. Example from Xenial: $ grep 'model name' /proc/cpuinfo model name : Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz $ dmesg ... [ 1.224044] usb 3-4: ep 0x81 - rounding interval to 64 microframes, ep desc says 80 microframes [ 1.677095] tsc: Refined TSC clocksource calibration: 3292.375 MHz [ 1.677134] clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x2f75298baf3, max_idle_ns: 440795322961 ns [ 2.677286] clocksource: Switched to clocksource tsc [ 12.784911] PM: Hibernation image not present or could not be loaded.

I also tried with "nohibernate", it's not related to hibernation. ** Tags removed: kernel-fixed-upstream ** Tags added: xenial -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
