The 5.0rc1 is now installed, but the kernel doesn't appear in the grub list, also after grub-update. dpkg reports it as installed.

The computer sometimes freezes completely and power button is the only escape. This happens when I scroll the mouse, press a button or moves the mouse (any event from the mouse). This can happen in any running program: Firefox, pdf-viewer, Libreoffice Writer... Most often this comes with my usb-to-ethernet LEDs switch off (during blink), but not always. Seems to be a collision event between my USB-mouse and USB-to-ethernet adapter, i.e mutex. An other computer without the USB-to-ethernet adapter never freezes. Configured in the same way. (I used Ubuntu 14.04 for a long time and this freeze never happened. In 18.04 this happens at least every two weeks. It is the same hardware.) $ uname -a Linux ubuntu 4.15.0-39-generic #42-Ubuntu SMP Tue Oct 23 15:48:01 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux $ lsb_release -rd Description: Ubuntu 18.04.1 LTS Release: 18.04 --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: user 5276 F.... pulseaudio /dev/snd/controlC0: user 5276 F.... pulseaudio CurrentDesktop: MATE DistroRelease: Ubuntu 18.04 MachineType: TOSHIBA SATELLITE Z30-B Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-42-generic root=/dev/mapper/hostname--vg--1542473018588400299-root ro quiet splash vt.handoff=1 ProcVersionSignature: Ubuntu 4.15.0-42.45-generic 4.15.18 RelatedPackageVersions: linux-restricted-modules-4.15.0-42-generic N/A linux-backports-modules-4.15.0-42-generic N/A linux-firmware 1.173.2 RfKill: 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no Tags: bionic Uname: Linux 4.15.0-42-generic x86_64 UnreportableReason: This report is about a package that is not installed.
