dmesg

I'm using Gentoo kernel 4.5, after resume from hibernation I have black screen. I tried two kernel versions 4.5.0-r1 and 4.5.3. In the end of dmesg after every resume I see:
[drm:radeon_dp_link_train] *ERROR* displayport link status failed
[drm:radeon_dp_link_train] *ERROR* clock recovery failed
Does displayport means DisplayPort(https://en.wikipedia.org/wiki/DisplayPort)? Because I don't have this in my laptop.

Does Ctrl-Alt-F1 help?
Comment 2 d9d9 2016-05-12 12:08:37 UTC 
No, I can't switch between tty's, I can log-in only via ssh.
Comment 3 d9d9 2016-05-18 18:30:49 UTC 
If I make DRM_TTM and DRM_RADEON as modules there is no any errors. So I think, there is no any issues.
