First of all, I do not use Ubuntu, I use Debian, but I thought it would be a nice input anyway, feel free to delete this if this don't help. I had the same problem the first reboot I did after a system update to:
Linux version 4.9.0-6-amd64 (debian-ker...@lists.debian.org) (gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1) ) #1 SMP Debian 4.9.88-1 (2018-04-29) Boot got stuck everytime at random: crng init, varying from 1min to 20min. A friend told me it was because the random pool was being populated everytime I booted and for some reason it was taking too long. I installed the havenge package (deb free repo) that contains an alternative algorithm to populate de RNG seeds. Apparently the problem is now solved, as my system is now booting in 13s. Hopefully this will be of some help. Anyway, if installing havenge does not work, you could purge it afterwards and no harm done... -- 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/1685794 Title: Boot delayed for about 90 seconds until 'random: crng init done' Status in linux package in Ubuntu: Confirmed Bug description: Shortened dmesg output, notice the unnaturally long delay before crng init finishes: [ 8.533630] Bluetooth: hci0: Intel Bluetooth firmware patch completed and activated [ 8.542239] input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input18 [ 8.542313] input: HDA Intel PCH Line as /devices/pci0000:00/0000:00:1b.0/sound/card1/input19 [ 8.542382] input: HDA Intel PCH Dock Line Out as /devices/pci0000:00/0000:00:1b.0/sound/card1/input20 [ 8.542449] input: HDA Intel PCH Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card1/input21 [ 8.544240] cdc_ether 2-6:2.0 usb0: register 'cdc_ether' at usb-0000:00:14.0-6, CDC Ethernet Device, 02:1e:10:1f:00:00 [ 8.544271] usbcore: registered new interface driver cdc_ether [ 8.637660] ieee80211 phy0: Selected rate control algorithm 'iwl-mvm-rs' [ 8.654022] input: HP WMI hotkeys as /devices/virtual/input/input22 [ 8.688226] cdc_ether 2-6:2.0 enp0s20u6c2: renamed from usb0 [ 8.713288] iwlwifi 0000:02:00.0 wlo1: renamed from wlan0 [ 9.804308] input: ST LIS3LV02DL Accelerometer as /devices/platform/lis3lv02d/input/input23 [ 98.327857] random: crng init done [ 98.330072] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 98.330073] Bluetooth: BNEP filters: protocol multicast [ 98.330077] Bluetooth: BNEP socket layer initialized [ 98.443281] kauditd_printk_skb: 90 callbacks suppressed [ 98.492927] IPv6: ADDRCONF(NETDEV_UP): enp0s25: link is not ready [ 98.681030] IPv6: ADDRCONF(NETDEV_UP): enp0s25: link is not ready [ 98.685672] IPv6: ADDRCONF(NETDEV_UP): enp0s20u6c2: link is not ready [ 98.685789] cdc_ether 2-6:2.0 enp0s20u6c2: kevent 12 may have been dropped [ 98.688384] IPv6: ADDRCONF(NETDEV_UP): wlo1: link is not ready [ 98.690915] iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: linux-image-4.10.0-19-generic 4.10.0-19.21 [modified: boot/vmlinuz-4.10.0-19-generic] ProcVersionSignature: Ubuntu 4.10.0-19.21-generic 4.10.8 Uname: Linux 4.10.0-19-generic x86_64 ApportVersion: 2.20.4-0ubuntu4 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-path', '/dev/snd/hwC1D0', '/dev/snd/pcmC1D0c', '/dev/snd/pcmC1D0p', '/dev/snd/controlC1', '/dev/snd/hwC0D0', '/dev/snd/pcmC0D8p', '/dev/snd/pcmC0D7p', '/dev/snd/pcmC0D3p', '/dev/snd/controlC0', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CurrentDesktop: Unity:Unity7 Date: Mon Apr 24 14:58:33 2017 EcryptfsInUse: Yes InstallationDate: Installed on 2017-04-18 (5 days ago) InstallationMedia: Ubuntu 17.04 "Zesty Zapus" - Release amd64 (20170412) MachineType: Hewlett-Packard HP EliteBook 840 G1 ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.10.0-19-generic.efi.signed root=UUID=9fb9fc1d-15a4-4e98-a2ae-bf572e0900d5 ro quiet splash vt.handoff=7 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
