[Sidefx-houdini-list] RE: Side Effects software crashes X

Where do I sign up for the support group?  Our systems group probably has 
blacklisted me by now.  ;-)

RedHat 7.3
Latest NVIDIA drivers (tried a whole bunch of drivers prior)
GeForce 6800 Ultra
2.4.32 kernel

The problem only occurred when we upgraded my kernel from 2.4.18-4 to 2.4.32. 
Nothing else changed other than kernel compile and install.  Removing Houdini 
fragment shader support didn't help neither.

Mplay crashes the system or puts X in a 100% CPU usage state when run on an 
image larger than random(seed) x random(seed).  Prior to kernel upgrade, mplay 
also put X in a 100% CPU usage but was no where as often as after the kernel 
upgrade.  Due to other interactions, downgrading the kernel is not an option.
