Description David Juran 2015-11-26 09:47:03 UTC 
Description of problem:
Once or twice a week, the graphics on my workstation locks up. In the log files the following messages are seen


Nov 26 09:51:10 localhost kernel: radeon 0000:01:00.0: ring 0 stalled for more than 10000msec
Nov 26 09:51:10 localhost kernel: radeon 0000:01:00.0: GPU lockup (current fence id 0x000000000002f38f last fence id 0x000000000002f391 on ring 0)

this message is repeated very fast

Then, a bit further down:

There's quite a few of these traces....

Comment 1 David Juran 2015-11-27 07:51:12 UTC 
Trying setting radeon.dpm=0 on the kernel command-line
Comment 2 David Juran 2015-11-27 08:20:14 UTC 
echo low > /sys/class/drm/card0/device/power_profile 
might also be a good idea unless you enjoy the sound of a jet-engine under your desk when dpm is disabled...
Comment 3 David Juran 2015-12-06 12:05:55 UTC 
This morning (well, it's a Sunday morning) similar issue happened again, with radeon.dpm disabled:

A large number of these backtraces exist... And then at some point, the kernel seem to have gone down entirely as the machine stopped responing to ping and also no further logs where available

Comment 5 David Juran 2015-12-11 07:30:16 UTC 
Trying with creating the file /etc/profile.d/radeon.sh with the following content:
export R600_DEBUG=nodma

and then rebooting

Fan seem to be running harder then usual but not as hard as when DPM was disabled
Comment 6 Jérôme Glisse 2015-12-11 15:35:02 UTC 
this is just usual GPU lockup, hard to debug, best thing to do is find the smallest use case that trigger it (like launching application X and doing Y and Z in it trigger the lockup). All the error message with ttm in backtrace are outcome of first GPU lockup. Sadly recovering GPU from lockup state is not reliable without magic reset, i do not think AMD released that for this generation.
Comment 7 David Juran 2016-02-27 09:38:56 UTC 
Not really a solution to the problem in the ATI driver but some months ago I just uninstalled xorg-x11-drv-ati, my understanding is that it then falls back upon the modesetting driver. This has worked flawless without any performance degradations that I can notice.
Comment 8 David Juran 2016-05-26 11:03:53 UTC 
I guess I spoke too soon, the problem still occurs with the modesetting driver, but my gut feeling is that it happens with much lower frequency
Comment 9 Fedora End Of Life 2016-11-24 13:45:16 UTC 
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. 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 EOL if it remains open with a Fedora  'version'
of '23'.

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.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 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 this bug is closed as described in the policy above.

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.
Comment 10 Fedora End Of Life 2016-12-20 16:18:38 UTC 
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
