           Summary: screen flickers all the time with desktop image
                    appearing only briefly
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: 3ntr0p13@gmail.com

Xorg.0.log

Machine is an Acer Aspire L5100 with an AMD Athlon 64 X2 Dual Core Processor
4000+ running a 64 bits debian sid.

The machine is a small factor desktop machine designed around laptop
components, so the graphic card is an integrated radeon x1200.

When running a linux vanilla kernel 2.6.34, the screen flickers all the time
making the machine unusable, while with kernel 2.6.33 such "flick to black"
event occured from time to time but most of the time the desktop was correctly
displayed.

radeon.new_pll=0 doesn't solve the problem
radeon.nomodeset=0 does

The problem was bisected to commit 383be5d1789d9a7a2e77dca1cb0aca89507d069e

The following packages version are installed:
xserver-xorg                           1:7.5+6
xserver-xorg-core                      2:1.7.7-1
xserver-xorg-video-radeon              1:6.13.0-2

Please find attached Xorg.0.log and dmesg for that machine (when booted on
2.6.34 with no radeon option).

Can you dump the following regs using avivotool in both kms and ums?  You can
get avivotool here:
http://cgit.freedesktop.org/~airlied/radeontool/
and most distros package it.
e.g.,
avivotool regmatch 0x0400 >> kms.out
avivotool regmatch 0x0404 >> kms.out
avivotool regmatch 0x0430 >> kms.out
avivotool regmatch 0x0438 >> kms.out
avivotool regmatch 0x043c >> kms.out
avivotool regmatch 0x0450 >> kms.out
avivotool regmatch 0x0410 >> kms.out
avivotool regmatch 0x0414 >> kms.out
avivotool regmatch 0x0434 >> kms.out
avivotool regmatch 0x0440 >> kms.out
avivotool regmatch 0x0444 >> kms.out
avivotool regmatch 0x0454 >> kms.out

Thanks Alex: I applied the patch on top of
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git and it
seems to fix the "flicker all the time issue" for me.
