           Product: Drivers
           Version: 2.5
    Kernel Version: 3.0.0-rc3
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: kernellist@neutrinus.com
        Regression: Yes


When running kernel versions => 3.0.0-rc3 there are a lot of artifacts on
screen when runing xorg. 

Kernel 3.0.0-rc2 and olders were producing clean image, right now there are
artifacts on screen, making any fonts/graphics unreadable. 3.0.0-rc[3-5] are
affected. It fully reproducible: just run kde :) Its happends everytime when I
switch 3.0.0-rc2 kernel to something newer.

I'm using debian AMD64 sid+experimental, kernel images from experimental. I'm
using xorg "radeon" driver. Mesa: 7.11~0-2.

There are no Ops, no strange logs in dmesg...

CPU: Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz

Are the artifacts captured in a screenshot, or only in a photograph taken from
the screen? It might be helpful if you could attach a picture showing the
artifacts either way.

Can you bisect?

both on screenshoot (using ksnapshot) and photograph

screenshoot: (~10MB)

(this is worst case - normally its not like whole windows garbaged)

yes :) (but it may take some time)

bisect log

skips were entered when xserver didn't even start properly - there was no way
to test if there are artefacts

Hope that it will help, if there is anything more that I can provide - just ask
for it.

I have just tested current master Linus tree - it still broken (so no hope that
it was already fixed in rc5+)

Would it help anything if I record video how the artifact change when using
system?

Can you provide Xorg.0.log and dmesg for such a failure?

Your log narrows things down somewhat, but I'm afraid there's still a couple of
potentially relevant changes in there.

Possibly.

git checkout 2f2f96d1ea72e6602ae440ac2867a6004edb37a1

all monitors went black, after few seconds backlight turns off, then on and
again few seconds of nothing (video:

I just checked kernel: vmlinuz-3.1.0-rc4-amd64 (from debian package) and
problem is still there...

Michel: yes, it looks similar
