That counts as a regression.
If things used to work, and they don't work, it's a regression. If
it's intentional, that just makes it worse.

.. and apparently this whole paragraph is completely bogus. It *does*
break things, and for normal people. That's what the bug report is all
about. So don't waffle about it.
BjÃrn, what's your setup? Is this perhaps solvable some other way?

Wrong. We don't break existing setups, and your attitude needs fixing.
Rafael, please get it reverted, or I will have to revert it. We have
*long* had a rule that we don't break things "in order to improve
things for others", and quite frankly, power management and ACPI in
particular was exactly *why* that rule was introduced, because the
whole "one step back, two steps forward" model does not work.
The problem needs to be solved some other way, and developers need to
f*cking stop with the "we can break peoples setups" mentality./
Hans, seriously. You have the wrong mental model. Fix it.
