Comment 6 for bug 1869032

I can finish running this test manually with autotest framework locally on this affected node modoc with 5.3.0-43:
AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ubuntu_kernel_selftests/control

And the test suite can finish without tripping this issue.

But during the test I noticed that there will be another "missing remote IOA" error in dmesg:

Maybe it's some combination issue with the sru-misc test suite, which contains the following tests and will be executed in the following order:
        'hwclock',
        'libhugetlbfs',
        'ubuntu_bpf_jit',
        'ubuntu_kernel_selftests',
        'ubuntu_lxc',
        'ubuntu_seccomp',
        'ubuntu_unionmount_ovlfs',
        'ubuntu_cts_kernel',
        'ubuntu_kvm_unit_tests',
