I have made now some tests and have figured out that on the slow booting kernels the console output is slow too. For example on "time dmesg" the slow kernels needs 3.5 seconds of real time while the fast kernels needs only 1 second of real time. Could it be that the slow console output causes the boot delay (I'm using GRUB_CMDLINE_LINUX_DEFAULT="elevator=cfq" so I'm getting more output than usual on booting)?
On testing the kernels I'm seeing a fast console output on linux- image-3.13.1-031301-generic (3.13.1-031301.201401291035) but not on linux-image-3.13.2-031302-generic (3.13.2-031302.201402061638). Also on the first one I'm seeing specific dmesg entries much earlier but the total booting time isn't that fast too. That makes me unsure if this issue has really something to do with the booting problem. Possibly this problem should be bisected first to test if after a fix the booting delay still exists on recent kernels? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1359754 Title: Booting time got slower with newer kernel versions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1359754/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
