dmesg output

randomly ( it's very rare, 90% of the time I don't have this error message ) I
can see these error messages on boot :

[    1.516518] [drm] Loading R200 Microcode
[    1.517953] [drm] radeon: ring at 0x00000000E0001000
[    1.665941] [drm:r100_ring_test] *ERROR* radeon: ring test failed

down CP.
[    1.812600] [drm] radeon: cp finalized
[    1.812629] [drm] radeon: cp finalized

but the boot process continues and I see no problem on KDE4.9.2 and 3d games,

this bug occurs since the update of ati-dri 9.0 and xorg packages 1.13 on my
archlinux 32 bits installation, before that I had never seen this kind of error
message

my system :

- archlinux 32 bits
- laptop pentium 4 2.4 ghz 1,2 Gb ram
- video card: ati radeon 9000 agp ( M9 rv250, r200 driver, dri2 enabled with
kms early start )
- SIS645DX chipset on motherboard

You can fin an attachment ( dmesg output ) with this message,

this bug may related to another ( startx problems ) :
