kernel oops triggered by read_all_sys in ubuntu_ltp/fs on J-5.15 / J-5.17 ARM64 "helo-kernel", "howzit-kernel"

[Po-Hsu Lin]

Issue found on Jammy 5.17.0-8-generic #8~22.04.2-Ubuntu and Jammy 5.15.0-27-generic with ARM64 node helo-kernel only.

It looks like this is hardware-specific.

The read_all_sys test in fs from ubuntu_ltp will cause kernel oops and test will timeout.

Steps to reproduce this:
git clone -b sru git://git.launchpad.net/~canonical-kernel-team/+git/ltp
cd ltp
make autotools
./configure
make
sudo make install
echo "read_all_sys read_all -d /sys -q -r 3" > /tmp/fs
sudo /opt/ltp/runltp -f /tmp/fs

Test log:
<<<test_start>>>

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1973153

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Po-Hsu Lin (cypressyew)]

This would fail on another ARM64 node howzit-kernel as well with Jammy 5.15.0-27-generic

But without the messages from mpt3sas_cm0

[dann frazier (dannf)]

A fix for this is currently queued in linux-next:

commit 1bbc21785b7336619fb6a67f1fff5afdaf229acc
Author: Lorenzo Pieralisi <email address hidden>
Date: Thu Apr 7 11:51:20 2022 +0100

    ACPI: sysfs: Fix BERT error region memory mapping

My plan is to propose this for stable after it lands during the merge window.

[dann frazier (dannf)]

Patches are now queued for all applicable stable trees (linux-4.14.y+)

[Po-Hsu Lin (cypressyew)]

Re-open ubuntu-kernel-tests task, we need to track this issue there for SRU.

[dann frazier (dannf)]

This fix is merged in v5.15.44

[dann frazier (dannf)]

The merging of 5.15.44 is tracked in bug 1981649

[Po-Hsu Lin (cypressyew)]

This failure can be found on J-oracle 5.15.0-1015 with ARM64 bare-metal BM.Standard.A1.160

[Po-Hsu Lin (cypressyew)]

Found this on Jammy 5.15.0-47.51 with node howzit-kernel.

[Po-Hsu Lin (cypressyew)]

For comment 9, I will need to verify this again manually. As I didn't see any report for ubuntu_ltp with node howzit-kernel for J-5.15.0-47.51

More update for sru-20220808, issue has gone with:
  * J-oracle 5.15.0-1017 with ARM64 bare-metal BM.Standard.A1.160

[Po-Hsu Lin (cypressyew)]

Verified with:

J-5.17.0-9.9~22.04.8:
 * howzit-kernel (GOOD, tested with generic kernel)

J-5.15.0-49.55:
 * helo-kernel (GOOD, tested with generic kernel)
 * howzit-kernel (GOOD, tested with generic-64k kernel)

F-hwe-5.15.0-48.54~20.04.1
 * howzit-kernel (GOOD, tested with generic-64k kernel)

Closing this bug, thanks!
