Bug #: 50891
Summary: Noisy lines on screen, Xorg unusable on Radeon HD 5670
Classification: Unclassified
Product: xorg
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: critical
Priority: medium
Component: Driver/Radeon
AssignedTo: xorg-driver-ati at lists.x.org

screenshot of the bug
When Xorg starts, instead of a normal display, I get only blank and noisy lines
(see screenshot).
I tried several things :
-proprietary driver : works without problems
-start with nomodeset : instead of noisy lines, I get a dark screen (see
attachement Xorg_log_nomodeset)
-normal start, I get the noisy lines, see Xorg_log
The Xorg logs were obtained by stopping Xorg (systemctl isolate
multi-user.target), and then using directly "Xorg -verbose 10 > log_file 2>&1"
When the bug occured, I got some "GPU lockup" errors on the terminal (not every
time) :

Versions :
Fedora 17, up to date
Kernel : 3.3.7, but I also tried 3.4.0 (recently released) and even 3.5-rc1
(from rahwhide) : the bug was exactly similar. It has been present in all the
kernel versions that I tested with that card (bought in september 2011)
#Xorg -version
X.Org X Server 1.12.0
Release Date: 2012-03-04
X Protocol Version 11, Revision 0
Build Operating System: x86-14 2.6.32-220.4.1.el6.x86_64
Current Operating System: Linux vmserver.grelot.net 3.4.0-1.fc17.x86_64 #1 SMP
Sun Jun 3 06:35:17 UTC 2012 x86_64
If necessary, I may use more recent kernels, bug I may need some help if it is
necessary to apply a patch :-)
I hope this will help!
