now.)

== SRU Justification BIONIC HWE, DISCO ==
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.

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 bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'. If the problem still exists,
change the tag 'verification-needed-xenial' to 'verification-failed-
xenial'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

(https://kernel.ubuntu.com/~cking/lp1827884/4.15). Just copy it to
xenial-proposed or something.
(Sorry for adding wrong tag, now I know we need to wait for kernel-bot

2. Issue is in upstream kernel
3. Issue not a kernel patch per-se (e.g. security fix, ubuntu sauce patch,

this probably is a hardware (or firmware?) specific issue.

Backport wiggle of upstream fix

== 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

Installed Bionic 18.04.2 i386 Desktop (using xubuntu) on a Lenovo

ways with video corruption being a main visible featured.
The CPU is a i3-2350M CPU, a 64 bit capable CPU, being booted with

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

appearing on 1 or more CPUs.

linux hwe i386 kernel 5.0.0-21.22~18.04.1 crashes on Lenovo x220
Status in linux package in Ubuntu:

Bug description:
== SRU Justification BIONIC HWE, DISCO ==
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.
== 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

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
disco' to 'verification-done-disco'. If the problem still exists, change
the tag 'verification-needed-disco' to 'verification-failed-disco'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

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

Bug description:
== SRU Justification BIONIC HWE, DISCO ==
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 https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1.20/ - less corruption and now the splash screen starts but as soon as splash transitions to the X display we get an immediate hang.
