Kernel Panic - Display Freeze/Lockup

Running with RHEL 4.0 ES update 4 (32bit) with the 2.6.11-1226 kernel. During normal operations were enountering a kernel panic which freeze our displays. I hooked up a laptop and captured the following panic from standard output:

console shuts up ...

I've contacted NVIDIA to help with the trouble-shooting and wonder if anyone else has had the same freeze or lock-up issue.

Using the Nvidia FX 1300 cards.

Thanks,
John

Many boxes, all using that display? No boxes using other displays?
