Ah, the perennial add-same-test-to-every-driver conundrum.
I think we are far enough along with MSI to _not_ do this anymore in
drivers.
The platforms with MSI problems should be discovered, made public, and
worked around.
Otherwise you hide the same problem, just for someone else to discover
with another component of the machine.
