drm/radeon/kms: need to set up ss on DP bridges as well
In the 3.4.4-1 release?
Yes, this patch was in 3.4.0. According to the upstream bug, it did not fix the problem for several people.
I stand here with this same problem. Computer goes to sleep and doesn't wake up the video driver. Computer is working as I can type and even reboot if I hit the right keys,
That freedesktop bug doesn't seem to be the same issue as this one. It sounds to me like that one is about the monitor not turning on at all. This one is about it working for a while and then not working, maybe when the screen locks and turns off.
I have an A8-3870 APU and kernel-3.5.2-1.fc17.x86_64. I was logged in and went away for a few minutes. When I came back the monitor was off and wouldn't turn back on. I checked the logs using ssh and found the messages mentioned above:
[ 1363.859176] [drm:radeon_dp_link_train_cr] *ERROR* clock recovery reached max voltage
[ 1363.859187] [drm:radeon_dp_link_train_cr] *ERROR* clock recovery failed
with 3.5.5-2.fc17.i686.PAE kernel (from koji) now i'm working two days without this problem, thus it seem bug is solved (to 3.5.5 Fedora kernel was perhaps bacported some radeon patches from 3.6 kernel).
Don't know when it got fixed because I was using the catalyst driver, but with 3.6.2, and with 3.6.6 it works like a charm.
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
