<pre>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:
