>Description:
I'm using a seven year old Gateway PC that has all Intel drivers, (video, audio, agp, pci, isa).  When I run "X -configure" it picks the "intel" video driver.  The chip set is ntel 82810-DC100 GMCH.  When I run it I get the following error in Xorg.0.log:

Error in I810WaitLpRing(), now is 2371005, start is 2369004

>How-To-Repeat:
Happens anytime you run Xorg with "intel" video driver.
