dmesg

Machine is the same as in bug report 28331 although with different software components: Acer Aspire L5100 with an AMD Athlon 64 X2 Dual Core Processor
4000+, this time running a 64 bits debian squeeze.

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 2.6.37-rc6, the screen flickers all the time
making the machine unusable, while with debian kernel 2.6.32-5 such "flick to black" event occur from time to time, making it annoying but usable.

While booting with radeon.modeset=0 the problem doesn't exhibits itself

The following packages version from debian squeeze are installed:
xserver-xorg 1:7.5+8
xserver-xorg-core 2:1.7.7-10
xserver-xorg-video-radeon 1:6.13.1-2+squeeze1

Please find attached Xorg.0.log, dmesg, register dumps for ums and kms for that machine (when booted on 2.6.37-rc6).

Gildas
