           Summary: [drm:radeon_crtc_page_flip] *ERROR* failed to reserve
                    new rbo buffer before flip
           Product: DRI
           Version: DRI CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)

I have a 780G chipset (HD3200), using xf86-video-ati 6.14.0 with Xserver 1.9,
kernel 2.6.37 and 2.6.38-rc4. Looking in my kern.log, I see regularly this

Just a me too on this, also seeing the same on my ArchLinux 64bit installation
with an Mobility Radeon X1400 PCIE and DRM Testing with KMS PageFlip enabled. 

ATI Dri version: 7.10.0.git20110206
Kernel version: 2.6.37-rc8-34105-g2b2fd60-dirty

i see those errors appear in my dmesg occasionally, and from what it appears
the 3D performance goes down a bit sometimes after they have appeared. noticed
by wobbly windows in compiz not being silk smooth after a couple of occurances.

When testing with latest drm and kernel, I can't find the error anymore.

I'm experiencing this error on my updated Debian Testing with an ATI R100
(RV200 4C57) and: 
kernel 3.1.0-1-486 
Mesa 7.11.2

I'm using no manual xorg.conf.

Are there also 'reserve failed' messages before the messages referenced in the
original report?

Do you notice any problem other than the messages?

No, there aren't. Is the only type of "reserve failed" I got.

>

Mhm.. seems not. I've noticed anything related with radeon but, you can check
in the attachment of my dmesg.

Add return value to error message

Please apply this debugging patch and post the value(s) of r when the message
occurs again.

After last kernel upgrade ( 3.2.0-1-486 with Debian patches ) I don't get the error messages anymore.

Would you like me to check the value of r with your patch using the previous kernel?

Great, let's assume for now it's been fixed.

> Would you like me to check the value of r with your patch using the previous kernel?

I don't think that's necessary. If you ever see the problem again with the newer kernel, it would be interesting to know the value of r though.
