dmesg from F13 latest nightly

Fedora 13 running lastest nightly compose, desktop-x86_64-20100310.20.iso. Plus I did a yum update on the xorg-x11-drv-ati. So I'm running:

kernel-2.6.33-1.fc13.x86_64
xorg-x11-drv-ati-6.13.0-0.23.20100219gite68d3a389.fc13.x86_64

Comment 6 craigjl77 2010-03-23 07:19:07 UTC

I have exactly the same problem. After latest yum update vga-0 lcd monitor displays wavy distortions. The distortions are more pronounced as the screen resolutions decrease.

Comment 10 Douglas Whitfield 2010-04-02 20:44:57 UTC

I have this too on the Compaq nc6400.  For what it's worth, this bug is also in Ubuntu Lucid: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/539350

This bug also applies to the HP nx9420

2.6.34-0.19.rc2.git4.fc14.x86_64 here.

Also, what's the deal with the fc14/fc13 stuff...some packages seem go one way and others the other...

Comment 11 craigjl77 2010-04-12 02:27:03 UTC

Note the problem goes away when you use this, 2.6.31.12-174.2.22.fc12.i686, Kernel.

Comment 12 Michal Schmidt 2010-04-15 10:21:27 UTC

I saw the same problem during the Radeon Test Day on my laptop with RS690M.

I bisected it to:
ebbe1cb936dfc96d809ccf4d64a9755f8ba0c0ff
drm/radeon/kms/atom: add support for spread spectrum (v2)

This commit itself was not testable, so I had to apply this patch too:
d11aa88b33b071d55181a7a482b9e7494888c10e
drm/radeon/kms/atom: fix potential oops in spread spectrum code


Then I found the bug is already fixed in 2.6.34-rc4 by commit:
267364ac17f6474c69b03034340f769b22f46105
drm/radeon/kms: further spread spectrum fixes

Comment 13 craigjl77 2010-04-15 10:33:37 UTC

So, when does 2.6.34 get released to the consumers?

Comment 14 Matěj Cepl 2010-04-15 13:40:41 UTC

> So, when does 2.6.34 get released to the consumers?    

Not in Fedora 13.

Comment 15 Leif Gruenwoldt 2010-04-15 14:51:42 UTC

(In reply to comment #14)
> Not in Fedora 13.    

Any chance of this being backported to a F13 kernel?

quick hack to disable spread spectrum

For now I'm using the attached simple patch which just disables spread spectrum. Here's a scratch kernel build (F-13, x86_64):
http://kojipkgs.fedoraproject.org/scratch/michich/task_2127062/

Comment 17 Michal Schmidt 2010-04-20 10:37:25 UTC

Dave Airlie backported the proper fix to F-13.
drm-radeon-ss-fix.patch is now in kernel-2.6.33.2-57.fc13:

http://koji.fedoraproject.org/koji/taskinfo?taskID=2127556

I have tested the x86_64 build on my RS690M and it works fine.

Sorry to bring the thread back to life but, is there a fix for this bug in FC12 or is the fix only available for FC13?
