Bug#481345: My bug (484049) may be a duplicate of this

2008-06-02 Thread Lee Cremeans
Sam, can you reproduce the bug, then SSH into the target machine and 
look for a block of text that mentions Error in I830WaitLpRing(), 
timeout for 2 seconds? I think this bug and my bug with scorched3d are 
related, but I'm not quite ready to mark mine as a duplicate yet.


For what it's worth, the G965 seems to be upset because of an invalid 
command, most likely because either the intel driver or Mesa overwhelmed 
it and overran the ring buffer, sending the G965's command sequencer 
spinning off into space. I'll do more investigating tonight to see who 
the guilty party is.

It's very hard to know where such a bug comes from. The error in
i830WaitLpRing is basically just a random GPU lockup which may be caused
by multiple bugs in Mesa or in the video driver. I usually don't merge
such bugs to avoid messing up their contents. We already have multiple
bug reports like these actually.
