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.
