Venice (Reality Engine) Graphics Panics

I'm running on a 4 processor R3000 Reality Engine in 1600x1200 60HZ 
mode and every once in a while the graphics engine decides to go south
for a while. This usually happens while running a GL program of some
sort. It's not limited to third party or my own software, SGI demos
crash it too. 

Here's a dump I got in the /usr/adm/SYSLOG for a program I wrote which
defined 500 128x128 16 bit (originally 32 bit) textures and rendered
121 textures every frame. The other dumps I get from SGI demos and stuff
look almost exactly the same.

Crazypete is the system name. For those curious, it's a little pond
near Menlo Park.

From here you get you're normal system startup...

Any InSight would be of great help. 

An InSight CD would be nice too. =:) When is the bug disk coming out anyway?
