From: Pierrick Bouvier <pierrick.bouv...@linaro.org> This test was randomly failing on our CI, and on dev machines, especially with QEMU debug builds.
>From the information collected, it's related to an implementation choice in edk2 QEMU virt support. The workaround is to disable KASLR, to avoid accessing protected memory. Note: this is *not* needed for the similar test_aarch64_rme_sbsaref. More information is available on the associated GitLab issue.
