Description of problem: I'm using F27 with 4.14 kernel without any problem. If I try to upgrade the kernel to the proposed 4.15 or the new 4.16 (shipped with F28), most of the times my laptop (Dell 5510) hangs at boot, becoming completely unresponsive (I have to hold the power button). Something like 1 boot on 3 goes fine and the PC runs smoothly. From the journal the last things I can read: mag 03 22:02:02 giacomo-linux audit[1]: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=systemd-random-seed comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' mag 03 22:02:02 giacomo-linux audit[1]: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=fedora-readonly comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' mag 03 22:02:02 giacomo-linux audit[1]: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=systemd-tmpfiles-setup-dev comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' mag 03 22:02:02 giacomo-linux systemd-journald[522]: System journal (/var/log/journal/0b5886a60d454e6fbe66d3ad4e96d331) is 2.4G, max 4.0G, 1.5G free. mag 03 22:02:02 giacomo-linux systemd-journald[522]: Time spent on flushing to /var is 41.569ms for 1108 entries. mag 03 22:02:02 giacomo-linux systemd[1]: Starting udev Coldplug all Devices... mag 03 22:02:02 giacomo-linux systemd[1]: Starting Configure read-only root support... mag 03 22:02:02 giacomo-linux systemd[1]: Starting Create Static Device Nodes in /dev... mag 03 22:02:02 giacomo-linux systemd[1]: Starting Flush Journal to Persistent Storage... mag 03 22:02:02 giacomo-linux audit[1]: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=systemd-remount-fs comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' mag 03 22:02:02 giacomo-linux systemd[1]: Started Remount Root and Kernel File Systems. mag 03 22:02:02 giacomo-linux kernel: BTRFS info (device sda4): disk space caching is enabled mag 03 22:02:02 giacomo-linux audit[1]: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=systemd-sysctl comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' mag 03 22:02:02 giacomo-linux systemd[1]: Started Apply Kernel Variables.

*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 27 kernel bugs. Fedora 27 has now been rebased to 4.17.7-100.fc27. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 28, and are still experiencing this issue, please change the version to Fedora 28. If you experience different issues, please open a new bug report for those.
Hi, I moved to FC28 and, unluckily, the bug is still here. 4.17.7
(In reply to giacomo82 from comment #2) > Hi, I moved to FC28 and, unluckily, the bug is still here. > 4.17.7 Sorry, I saved without finishing. I moved to FC28 with 4.17.7 kernel and I still cannot boot most of the times. Now I have to manually install 4.14.18-300 (from FC27) to be able to use my PC. Thanks.

Hi, I can confirm the bug has been resolved with the 4.18 kernel. It boots normally. Thanks.
