So the test is failing as root on Intel, and the log output is
extensive. I'd prefer not to have the log output, so we may need to
work past some known broken items. Otherwise, the change looks okay,
but there are inconsistencies: `grep -q "<not supported>"` is used in
the existing code, while `grep -q "not supported"` is used here.

Thanks,
