No, you're right... I'm not sure I've seen it for real now...
will try harder.

I added a retry count in the while loop, and now the client
exits with an error. The log looks like this:
uploadSubImage( 0xdfb09828, 0xdb1b2808 ) level/width/height/face =
0/1024/1024/0
uploadSubImage: image data is in normal memory
upload image: 1024,1024 at 0,0
upload blit: 1024,1024 at 0,0
blit ofs: 0xe3866000 level: 0/0
DRM_RADEON_TEXTURE: again!
DRM_RADEON_TEXTURE: again!
DRM_RADEON_TEXTURE: again!
DRM_RADEON_TEXTURE: return = -11
offset=0xe3866000
image width=1024 height=1024
blit width=1024 height=1024 data=0xd9fff200
BTW, isn't 1024x1024 too big for a texture???

Is the log attached to the previous comment useful?
Or do you need me to add a printf in a more specific place?
