Issue found on 5.8.0-54-generic proposed ARM64 kernel with node "helo", "wright"

This issue does not exist in 5.8.0-53.60 so this might be a regression.

Test case:
  Create a KVM with the following command:
    uvt-kvm create bjf-test release=groovy arch=arm64
  Or you can run the ubuntu_kvm_smoke_test with autotest:
    git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest-client-tests -b master-next
    git clone --depth=1 git://kernel.ubuntu.com/ubuntu/autotest
    rm -fr autotest/client/tests
    ln -sf ~/autotest-client-tests autotest/client/tests
    sudo apt-get install git python-minimal -y || sudo apt install python2 -y
    AUTOTEST_PATH=/home/ubuntu/autotest sudo -E autotest/client/autotest-local --verbose autotest/client/tests/ubuntu_kvm_smoke_test/control

This is 100% reproducible on ARM64, 4 out of 4 attempts (twice on each nodes).
