[Bug 557266] Re: [Radeon kernel module] drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream

[Fabio Pedretti]

** Description changed:

+ Note: this bug is fixed in kernel 2.6.36, but it's still not fixed in the 2.6.35.x series (at least up to 2.6.35.7). To fix it in 2.6.35.x it needs this kernel patch:
+ http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=a41ceb1c17af06a17c0d88e987215ef20b93c471
+ 
+ Also this patch (scheduled for 2.6.37) is also needed to fix a similar issue on r200:
+ http://lists.freedesktop.org/archives/dri-devel/2010-October/005069.html

  Note: if you are getting "drmRadeonCmdBuffer: -12" this is another
  problem see bug #533784.

  I am getting this:
  drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info.
  when trying to start the game 0ad or douze map with sauerbraten (with shaders enabled).
  
  dmesg shows this after 0ad crash:
  [  204.087282] [drm:r100_cs_track_check] *ERROR* [drm] Buffer too small for color buffer 0 (need 4190208 have 3145728) !

  [  204.087300] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
  
  and this with sauerbraten:
