Same here, downgrading to 4.4 from Xenial improved the situation (boot still feels a little slower than Xenial though, maybe because of the NetworkManager bug). I use a 7 years old desktop computer based on a Gigabyte motherboard and AMD Phenom II X4 955 CPU, So it's not Thinkpad- related.
(From GRUB to lightdm used to be 7 seconds in 16.04, but using Kernel 4.8 and the new network manager it feels more like 20 secs. Also, the Unity 7+Chromium launch used to take just very few seconds, now it's a noticable delay with only the wallpaper showing, no matter which kernel I use, so that's unrelated. Anyway, booting my computer has just become a lot less fun even though I removed Apache 2 and Tomcat. :( ) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1626436 Title: [4.8 regression] boot has become very slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1626436/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
