Its quite the opposite.

If bug is still there 6 months after the commits that broke the drivers,
(making an old bug visible) that means that people never realized the
bug was there.

I understand a distro maintainer has its own choices, but for upstream
kernel we want to have early reports.

This bug is fatal and a security issue. BUG() is appropriate.

If the driver cant be fixed, it should be marked broken.

So I personally NACKed patch to hide the bug, trying to be friendly to
the user.
