Title:
Kernel panic during checkbox stress_ng_test on Grace running noble 6.8
(arm64+largemem) kernel

Status in linux source package in Noble:

Bug description:
A kernel oops and panic occurred during 22.04 SoC certification on
Gunyolk (Grace/Grace) with 6.8 kernel, arm64+largemem variant

Steps to reproduce:
Run (as root) the following commands:

add-apt-repository -y ppa:checkbox-dev/stable
apt-add-repository -y ppa:firmware-testing-team/ppa-fwts-stable
apt update
apt install -y canonical-certification-server
/usr/lib/checkbox-provider-base/bin/stress_ng_test.py disk --device dm-0 --base-time 240

stress_ng_test caused a kernel panic after about 5 minutes. I have
attached dmesg output from my reproducer to this report.

Initially, this was identified via a panic during the above test,
which was running as part of a run of certify-soc-22.04.

Attached is a tarball containing:

- apport.linux-image-6.8.0-11-generic-64k.kzsondji.apport: The output of `ubuntu-bug linux` on the machine (after reboot)
- reproduced-dmesg.202403201942: The dmesg output captured by kdump when I reproduced my original issue by running only the single stress_ng_test.py command above (not the entire cert suite)
- original-dmesg.txt: The dmesg output I captured when the stress_ng_test originally failed during the full cert suite run
