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 from remote.) I'm not sure why 'ip=dhcp' causes that delay. I was able to rule out the initramfs—I modified /usr/share/initramfs-tools/init to print the contents of /proc/uptime as early as possible. According to the logged time, init doesn't start running until after the 10 second pause (unless mounting /proc takes 10 seconds when ip=dhcp is in the command line arguments, which I doubt). -- 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
