Tried: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.2.3/ No splash screen, and screen turns off after several seconds and machine is completely hung after that.
Most probably all of this is a regression in the i915 driver for 32 bit platforms with Intel® HD Graphics 3000 ** Changed in: linux (Ubuntu) Importance: Undecided => Critical -- 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/1838115 Title: linux hwe i386 kernel 5.0.0-21.22~18.04.1 crashes on Lenovo x220 Status in linux package in Ubuntu: Incomplete Bug description: Installed Bionic 18.04.2 i386 Desktop (using xubuntu) on a Lenovo x220i and upgraded to proposed. The 5.0.0.22 kernel crashes in various ways with video corruption being a main visible featured. The CPU is a i3-2350M CPU, a 64 bit capable CPU, being booted with EUFI firmware disabled, so using traditional BIOS. 1. Crashes can be just complete hangs, no ability to switch virtual console 2. Crashes may just result in screen turning off, no video and hang and/or reboot 3. Crashes sometimes allow virtual console. Can see watchdog hang checks appearing on 1 or more CPUs. Tried the i386 https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D kernels: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.0.21/ - same issue https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.20.17/ - same issue https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19.61/ - OK We therefore can conclude: 1. Issue appears between 4.19.61 and 4.20.17 2. Issue is in upstream kernel 3. Issue not a kernel patch per-se (e.g. security fix, ubuntu sauce patch, etc) I repeated this with a VM installation and I don't see the issue, so this probably is a hardware (or firmware?) specific issue.
