I use OpenGL 3D textures coupled with shader processing for color
conversions and some effects in my company's real-time video mixing
application.
It has been working great on thousands macs around the world for
years - but it now totally fails on my MacBook Pro 2.2 /
GeForce8600M, running 10.5.2:
Using OpenGL Profiler, I can clearly see my 3D textures are loaded
correctly, but once a shader accesses a texture, my Mac display
totally freezes, and the system log indicates:

... and so on, with no possible recovery, the only choice I have then
is to reboot via ssh.
Then, I made some tests, and the only way I can use 3D textures
without getting the graphics to freeze is to create a 3D texture with
depth 1 (one slice) :-/
I found tens of posts on various forums complaining about the same
graphics freezing problem on MBP/GeForce (while playing games, using
iPhoto, etc), so I'm wondering if there's not a graphics driver
problem somehow.
Did someone experience this kind of problem?
