Comment 423 for bug 1776563

Something doesnt sound right here, it's been over a year that this problem is known and nobody from AMD team commented on this, not even that they are working on it. Now out of a sudden one of their engineers claims they solved it but doesnt attach any kernel patch or info on the issue, just marks it as fix released. Another thing that is weird is that we are almost sure its a BIOS issue according to posts above, so this "fix" might be the same thing that ivrs kernel options do.
As for the issue you can verify its existance by the buzzing sound that power components do on the Acer's mainboard when ACPI doesnt work like it should. At Windows 10 the buzzing sound if you take close attention exists where the power management works correctly.
