Indeed, it's pretty much impossible for that change to cause the problem.

Most likely, the issue with amdgpu.dc=0 happens with some probability < 100%,
so you'd have to test longer / several times before declaring a commit as good.
(A commit where the problem occurs can immediately be marked as bad)
