This bug also happened when ran celestia with starting the desktop.The failure message is"intel_bufmgr_fake.c:392: Error waiting for fence: Device or resource busy.Aborting" . But it work well with nude X.(steps: xinit& ; celestia)
Comment 4 Gordon Jin 2008-10-22 00:42:15 UTC 
This happens on all of machines we tested: G45, GM45, GM965, Q965, 945GM.
It seems running with nude X may delay the triggered time.
Comment 5 Gordon Jin 2008-10-23 22:49:03 UTC 
This works fine with mesa_7_2_branch.
Comment 6 haihao 2008-10-24 01:45:43 UTC 
Seems it works fine if setting EXANoComposite to true in xorg.conf.

Comment 8 lin, jiewen 2008-10-28 02:25:05 UTC 
But , with gem, setting EXANoComposite to true in xorg.conf just make the game run further ,it hangs X at last.(about 40 minutes)
