Another report: https://bugzilla.redhat.com/show_bug.cgi?id=2241279
From all those links it seems quite a lot of users with Dell machines
are affected by this problem.

Thomas, turns out that bisection result was slightly wrong: a recheck
confirmed that the regression is actually caused by 45e34c8af58f23
