I've got a similar issue in that there's a pause of around 90 seconds during boot, though the messages either side of the pause are different. Thing is, there's no way of knowing whether the messages either side are even relevant - I can't believe that an almost identical length pause is not related to this issue though. I'm using 17.04 that was upgraded, though after the upgrade I also swapped the motherboard/processor to an Asus Prime X370-Pro and Ryzen 7 1700. I'm now using mainline kernel 4.11.0-041100-generic but the delay was also there with the stock 4.10.
The messages either side of the pause for me are: [ 11.667273] input: HDA NVidia HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:03.1/0000:28:00.1/sound/card0/input15 [ 11.667317] input: HDA NVidia HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:03.1/0000:28:00.1/sound/card0/input16 [ 11.667350] input: HDA NVidia HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:03.1/0000:28:00.1/sound/card0/input17 [ 11.971125] input: gspca_zc3xx as /devices/pci0000:00/0000:00:07.1/0000:29:00.3/usb5/5-2/5-2.4/input/input18 [ 11.971454] usbcore: registered new interface driver gspca_zc3xx [ 12.022162] usbcore: registered new interface driver snd-usb-audio [ 101.921672] IPv6: ADDRCONF(NETDEV_UP): enp38s0: link is not ready [ 101.923166] NVRM: Your system is not currently configured to drive a VGA console [ 101.923168] NVRM: on the primary VGA device.

I've tried disabling on-board audio ( it's an S1220A ) and the USB 3.1 chip, because they're fairly new and I thought one of them may be the problem... but neither made any difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1685794 Title: Boot delayed for about 90 seconds until 'random: crng init done' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1685794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
