ExtremeTech report AMD's subreddit has been buzzing recently about various Radeon driver issues. The biggest issue seems to be the occurence of a black screen, which forces the user to do a hard reboot:
For those of you just tuning in, the AMD subreddit has been buzzing lately about various issues and instabilities affecting the Radeon driver stack. Complaints on Reddit have often centered around a black screen problem that can leave a player with no choice but to hard reboot. While the system hasn’t necessarily crashed, the display is reportedly unresponsive and will not turn back on. A number of users have unhappily been discussing these problems on reddit. Some of these complaints have been popping up for awhile, with black screens mentioned in threads dating from August, but they seem to have gotten more numerous recently.
AMD confirmed the issues and said they're investigating the matter.
Stability of our drivers is a key priority for our software team. They are monitoring forum discussions closely, including the black screen and other issues users are reporting, and we are actively identifying and working on fixes. As soon as we have more information to share, we will let you know. We encourage users to report issues they are experiencing here [http://amd.com/report] so that our team can investigate.
