Description Bogdan Marinov 2011-02-14 04:30:37 UTC

A number of crashes have been reported in the Stellarium bug tracker by people who use Radeon graphics cards on Ubuntu.

Could someone please look into these bugs and find if they are known issues or not?

A representative is this bug report:
https://bugs.launchpad.net/ubuntu/+source/stellarium/+bug/481669
(see the comments for examples of different behavior)

Secondary examples include:
https://bugs.launchpad.net/ubuntu/+source/stellarium/+bug/481669
https://bugs.launchpad.net/ubuntu/+source/stellarium/+bug/643203
https://bugs.launchpad.net/ubuntu/+source/stellarium/+bug/657834
https://bugs.launchpad.net/ubuntu/+source/stellarium/+bug/658975
https://bugs.launchpad.net/ubuntu/+source/stellarium/+bug/711913

There seem to be two issues that may be separate or may have a common cause:

The first causes the following message in the log:

drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info.

dmesg output reported by the same user is:

[ 2054.358680] [drm:r100_cs_track_check] *ERROR* [drm] Buffer too small for color buffer 0 (need 393216 have 16384) !
[ 2054.358692] [drm:r100_cs_track_check] *ERROR* [drm] color buffer 0 (128 4 0 768)
[ 2054.358697] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

The other typical message is:

stellarium: ../../radeon/radeon_cs_gem.c:181: cs_gem_write_reloc: Assertion `boi->space_accounted' failed.
Aborted

Any ideas?

These should be already fixed in newer linux/mesa shipping with Ubuntu natty:

At my place, Stellarium 0.10.6 is working perfectly on both r200 and r600 with Linux kernel 2.6.38-rc3.
I don't even need to change the configuration any more (some time ago I had to disable "use_qpaintenginegl2" on r600).

With an older kernel 2.6.36 on r200 I'm getting
 [drm:r100_cs_track_texture_check] *ERROR* No texture bound to unit 1
 [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
