@rhansen, sorry, it turns out you were right! ip= is what's causing my kernel delay. I even tried without an initramfs to verify it, and it caused 10 seconds of delay before the kernel panic because of the missing initramfs.
I'll try to gather more info about it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1259861 Title: 5-10 second delay in kernel boot Status in linux package in Ubuntu: Confirmed Bug description: In Trusty I see a big delay while the kernel boots that I did not see back in Precise. Some people have been experiencing this in Saucy too, so I don't know exactly when it started happening. Excerpt from dmesg: [ 3.740100] Switched to clocksource tsc [ 14.208118] PM: Hibernation image not present or could not be loaded. [ 14.208885] Freeing unused kernel memory: 864K (c19ac000 - c1a84000) The exact messages above don't matter, they are different on different boots or on different machines. It even happens with e.g. $ sudo kvm -m 768 -cdrom trusty-desktop-i386.iso My current kernel is Linux server 3.12.0-7-generic #15-Ubuntu SMP Sun Dec 8 23:42:09 UTC 2013 i686 i686 i686 GNU/Linux ...but the exact version, maybe from 3.8 to 3.12+, shouldn't matter, just run `dmesg` yourself and check if there's a big delay there.
