Comment (by kallisti5):

 Hm.  We don't touch GPU Power Management for this very reason. (Letting
 the AtomBIOS manage the power on it's own)    I'll reach out to my AMD
 contacts to see if it is a known issue.

 It could be that the laptop vendor kept the voltages a bit too high to
 boost fps and didn't adjust the ASIC settings to match this adjustment.  A
 lot of vendors only test their machines running "Windows and the stock
 drivers" thus missing these kinds of bugs.  Linux likely doesn't see the
 issue as it takes over power management and likely has a wider safety
 threshold than the windows drivers.

 The only solition in this case would be to take over the GPU power
 management, but a lot of code needs to be written to do that and a *LOT*
 of testing as we would be more likely to overheat a wider range of
