          Priority: medium
            Bug ID: 66945
          Assignee: dri-devel@lists.freedesktop.org
           Summary: Heavy artifacts and unusable graphics system with the
                    latest DPM changes
          Severity: blocker
    Classification: Unclassified
                OS: Linux (All)
          Reporter: tobi@slackeee.de
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: DRM/Radeon
           Product: DRI

Using the latest drm-fixes-3.11 and drm-next-3.11 I get heavy artifacts as soon
as the radeon module is loaded, leaving my system unusable. Only the graphics
system stops to work, SSH connections to the system still work.

Hardware: Radeon HD6870 (01:00.0 VGA compatible controller: Advanced Micro
Devices [AMD] nee ATI Barts XT [ATI Radeon HD 6800 Series])
Software: Slackware -current

I got these error messages from dmesg:

Are you using radeon as a module or built into the kernel?

I use it as a module. Will test it inbuilt ASAP, needs some minutes to compile.

OK, took me some time to figure out that I also need the firmware inbuilt (and
which one, isn't quite obvious that I need firmware from BARTS, BTC and SUMO to
boot).
Anyways, problem persists, same errors in dmesg. If you want to see how it
actually looks, I have made a short video (sorry for the bad quality, need a
better camera): http://slackeee.de/public/drm-next-3.11.mp4

Sorry, no need to do that, modules should be fine.  Sometimes there are
problems with firmware when the driver is built in.

I have this issue too (same card), and I made a comment about it in one of the
Phoronix threads mentioning that the problem started post wip-5 patch-set.

Having read most of the other related threads, I've noticed that most/all
owners who try enabling DPM with a 6870 run into this problem.

If any other information is needed to find a commonality from whence this issue
originates (separate from OPs), let me know an I'll attach the needed logs.

add module parameter to disable aspm

Try this patch which adds a new module parameter to disable aspm.  Add
radeon.aspm=0 to your kernel command line in grub to disable aspm support.

The issue still persists for me after using that patch and disabling aspm. I've
attached a dmesg log taken after booting (to console, no X) using a 3.10
kernel, patched with the latest changes from the drm-fixes-3.11 branch (a01c34)
and your aspm patch. And I've also attached the output from lspci since mine
differs from OPs.

I'm still kind of new to the whole patching thing (I'm a newb) so there's a
chance that I may have done something wrong, but everything seemed like it went
OK to me.
