Installed Bionic 18.04.2 i386 Desktop 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. |

== Fix ==
Backport wiggle of upstream fix
3f8fd02b1bf1d7ba964485a56f2f4b53ae88c167 ("mm/vmalloc: Sync unmappings in __purge_vmap_area_lazy()")
== Test ==
Without the fix, i386 xubuntu on various Lenovo platforms crash during early boot with random video corruption, hangs,lockups or even reboots.
With the fix, it boots fine.
== Regression Potential ==
Higher than normal as this touches the mm sync and the fix has only just hit upstream so it has not much of a soak test. Testing with this shows it fixes a kitten killer breakage, so I think the risk vs benefit is worth considering |
