BSOD Crash when Gaming using Radeon VII with FreeSync On
Issue Description: My PC have BSOD issue after I replace my Vega64 with Radeon VII. The problem occurred randomly when gaming, following these stages:
Screen turns black and lose signal, program (like Skype/Discord, I can tell with my friend even) still work. (about 30 seconds)
PC freeze and program will no longer work. (about 1-2 minutes)
PC restart, and I can find BSOD dump file.
There is two kind of BSOD, these message are extract from BlueScreenView:
0x00000116 caused by driver : dxgkrnl.sys
0x00000EA caused by driver : atikmdag.sys, THREAD_STUCK_IN_DEVICE_DRIVER
Temporary Solution: After a lot of test, Finally I found that the FreeSync would be the reason of this problem, turn off FreeSync on my monitor stop BSOD occurred. However, I think this should be the driver problem because there are no issue when I use Vega64 with FreeSync on.

Another thing is that the LG 27UK850-W monitor has two FreeSync mode: extended and basic, I don't know if this would be a problem, but I always use extended mode before on Vega64.
