Description Ryan McAdams 2017-01-03 17:38:27 UTC

User-Agent:       Mozilla/5.0 (X11; Fedora; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36
Build Identifier: 

Fedora 25 has been running fine on my MacBook Pro, however after running the latest updates and picking up kernel 4.8.15-300 the graphics flicker non stop, making the desktop unusable.  If I boot to the previous kernel (4.8.6-300) the issue goes away completely.

LSPCI of VGA:

# lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus XT [Radeon HD 8870M / R9 M270X/M370X] (rev 83)


Reproducible: Always

Steps to Reproduce:
1.  Install Fedora 25 on Macbook Pro
2.  dnf update to kernel 4.8.15-300
3.  Reboot
Actual Results:  
Screen flickers non stop

Expected Results:  
Screen should not flicker
