BSOD 0xCA_2 on multiple machines

We have multiple users in our environment that have been getting BSOD's with corrupt dump files. They all point to 0xCA_2 and they are not doing anything specific when it happens. We have full dumps enabled so it will take very long to upload/download. I have copied the results of the debugger below. If someone can give me commands to type in, I can post my findings....

Kernel Complete Dump File: Full address space is available

PNP_DETECTED_FATAL_ERROR (ca)
PnP encountered a severe error, either as a result of a problem in a driver or
a problem in PnP itself. The first argument describes the nature of the
problem, the second argument is the address of the PDO. The other arguments
vary depending on argument 1.
Arguments:
Arg1: 0000000000000002, Invalid PDO
An API which requires a PDO has been called with either an FDO,
a PDO which hasn't been initialized yet (returned to PnP in a
QueryDeviceRelation/BusRelations), or some random piece of
memory.
Arg2: fffffa800be44050, Purported PDO.
Arg3: 0000000000000000, Driver object.
Arg4: 0000000000000000
