vxWorks kernel task exception

[BEEKMAN]

We've been trying to get our old robot to work with the new cRIO image and driver station, but we keep getting the kernel level task exception:

program
Exception current instruction address: 0x00000000
Machine Status Register: 0x0008b032
Condition Register: 0x22000848
Task: 0x2254120 "FRC_RobotTask"
0x2254120 (FRC_RobotTask): task 0x2254120 has had a failure and has been stopped.
0x2254120 (FRC_RobotTask): fatal kernel task-level exception!

We program the robot in c++ and we've tried multiple versions of last year's code along with some new of the new examples. The cRIO has been imaged multiple times from different computers. Our jaguars have also been updated to the new firmware (we use CAN via serial).

A similar exception has also been generated by the "paramTask" for the camera, which has also been updated.

Any help would be greatly appreciated

Edit: The problem appears to be coming from setting the jaguars in PercentVBus mode.
