I should have been more careful while applying. The aarch64 host failure for this is not
transient as I first assumed:
PASS 5 qtest-aarch64/bios-tables-test /aarch64/acpi/virt/oem-fields
qemu-system-aarch64: kvm_init_vcpu: kvm_arch_init_vcpu failed (0): Invalid argument
Broken pipe
ERROR qtest-aarch64/bios-tables-test - too few tests run (expected 6, got 5)
make: *** [Makefile.mtest:312: run-test-37] Error 1
