Anyone have an idea what a "Stack Trace" is and how I can debug a stack
trace? I'm getting a stop error BSOD similar to the following:

Bug Check 0xB8: ATTEMPTED_SWITCH_FROM_DPC
The ATTEMPTED_SWITCH_FROM_DPC bug check has a value of 0x000000B8. This
indicates that an illegal operation was attempted by a delayed procedure
call (DPC) routine.
Parameters
None
Cause
A wait operation, attach process, or yield was attempted from a DPC routine.
This is an illegal operation.
Resolving the Problem
The stack trace will lead to the code in the original DPC routine that
caused the error.

Thanks,
Johnny
