** Description changed: Ubuntu freezes at the login screen or, if one is quick enough, shortly after typing a few chars of the password. Sometimes nothing except the power button works, at times I could reboot via endless massaging of sysrq + b. Last good kernel: 4.15.0-13 Mainline 4.16.3 is also affected. Mainline 4.17rc1 is good again. --- lsb_release -rd Description: Ubuntu Bionic Beaver (development branch) Release: 18.04 + --- + ApportVersion: 2.20.9-0ubuntu6 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: mfederle 14667 F.... pulseaudio + CurrentDesktop: communitheme:ubuntu:GNOME + DistroRelease: Ubuntu 18.04 + InstallationDate: Installed on 2018-03-15 (37 days ago) + InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Alpha amd64 (20180314) + Lsusb: + Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub + Bus 001 Device 003: ID 0489:e0a2 Foxconn / Hon Hai + Bus 001 Device 002: ID 0bda:58f4 Realtek Semiconductor Corp. + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + MachineType: Dell Inc.
