I'm running everything from the xorg-edgers ppa + 2.6.36-rc2 + Firefox 4.0b6 This happened a while ago with 2.6.35 also. You have to go to about:config and set webgl.enabled_for_all_sites first Example URL where it crashes: http://www.ibiblio.org/e-notes/webgl/julia.html [ 574.327053] radeon 0000:02:00.0: r600_cs_track_check:287 mask 0x0000000F | 0x0000000F no cb for 0 [ 574.327058] radeon 0000:02:00.0: r600_packet3_check:1242 invalid cmd stream 451 [ 574.327060] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
It's also happening while trying to start Counter-Strike through wine. Note that it works the first time I start the game, but next ones are stepping onto this bug (I have to reboot my machine to play CS again). Ubuntu Maverick + xorg-edgers + HD3870 (r600), I'm using r600c driver. Tried also with mesa from git master. This bug was happening to me for a loong time (months), but I forgot to report it :)
This seems to have been fixed at least to some part now, several WebGL demos work fine! Gustaw: since we have to such different scenarios I think you should open a new bug for that.
