--- Comment #165 from MAD adamczuk@tlen.pl --- 4.10.0-28-generic [AMD/ATI] Tahiti LE [Radeon HD 7870 XT]
I have the same problem with this card.
On amdgpu I got black screen. But monitor remains on. I can log in via ssh and all.
On radeon first I get screen full of colourful pixels, then black screen, then monitor says no-signal and goes stand-by. And then pc hangs and I can no longer log in via ssh.
On radeon there are a lot of radeon 0000:01:00.0: ring 3 stalled for more than 10036msec kinda logs in dmesg. But on amdgpu there is nothing interesting really. It seems like it almost works, except for the black screen ;)
I think I'm gonna try fresh kernel from padoka ppa next. When I have some free time.
