Marked all tasks invalid. It's been over 2 years and no further update
from the tester who reported this initially. One can only presume it's
been resolved by some update to the kernel, or was not kernel related
and resolved itself by other means. If this appears again, we'll open a
fresh bug.

I added a nomination for Xenial, but that may not be the right way (I'm
not sure how to add a Xenial task like the Bionic task already added.
But this is a regression in as much as on Xenial this does not occur on
the 4.4 kernel but shows up at least in the 4.15 HWE kernel. For Bionic
it seems
