Description Sven Arvidsson 2010-09-05 13:01:57 UTC 
As mentioned in bug 28517, there's one (minor) problem remaining in Savage 2. Setting "Shadow Quality" to medium or higher results in 

 radeon: The kernel rejected CS, see dmesg for more information.

dmesg:
 Sep  5 21:56:46 zoe kernel: [97451.007942] [drm:r100_cs_track_check] *ERROR* [drm] Buffer too small for color buffer 0 (need 4194304 have 3145728) !
 Sep  5 21:56:46 zoe kernel: [97451.007946] [drm:r100_cs_track_check] *ERROR* [drm] color buffer 0 (1024 4 0 1024)
 Sep  5 21:56:46 zoe kernel: [97451.007947] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

This causes part of the game to stop being redrawn and graphics seems to "smear" across the menu.

Yeah, there are a few other bug reports I have filed where the same error appears "Buffer too small for color buffer", not sure if it's the same bug or just similar symptoms?

Could you possibly test this kernel patch:

http://lists.freedesktop.org/archives/dri-devel/2010-September/003830.html

I am 99% sure it fixes this bug, but I haven't tested it myself.
Comment 4 Sven Arvidsson 2010-09-12 12:15:23 UTC 
Sure enough, game is working fine with shadow quality on any setting now!

If you would, reply to that patch email with your Tested-By: tag, or just give it here.

We'll try to get that patch included in the next kernel. Closing.
